I was able to replicate this issue
I strongly suspect this is a bug since I can verify that Animate 2 was working correctly until the most recent update, so I will make a report as soon as possible
If anyone has more information about this, please let me know. Thank you
My intent for Animate 2 is to be a more lightweight, memory-efficient and relatively simple alternative to the default animation script, but this came at a cost of removing some of the functionality as you correctly noted 
The ideal use-case for Animate 2 are games with a set animation style (as in, predetermined by the game developer), which won’t require the other capabilities the default animation script provides thus will save a bit of memory and hopefully also gain a slight performance improvement by using Animate 2
March 24th, 2024 Update
Bug fix:
@sonicdoidao2004 You’ll enjoy this update 
More details about the bug fix:
I don’t think this works anymore with Roblox’s new TextChatService. I’ve been looking everywhere for an alternative and nothing worked as good as the Animate script for emotes.
Just now, I’ve ran a test (both in Studio and using the Player), and Animate 2 worked with TextChatService without encountering any issues. Are you experiencing a bug when using Animate 2 with TextChatService enabled?
The emotes I tested were: dance, dance2, dance3, laugh, point, wave, cheer
Hey! Sorry, I should’ve added more to my reply, yes, the default emotes work, however when you try and add more custom emotes (including the normal Animate script) it no longer allows it, I created a post yesterday regarding it. If you figure out a solution it would be awesome 
Currently doing my best to try to add custom emote support, but I’m stuck in a dead end due to this error:
Failed to load animation with sanitized ID rbxassetid://3576968026: AnimationClip loaded is not valid.
Which is odd since the animation ID is for an emote created by Roblox (and is equipped in my inventory), which should be exempt from the sanitized ID error. The default animation script doesn’t encounter this error when it loads the animations, so I’m investigating it to try to see how it avoids it
I also tried using Humanoid:PlayEmote, but it kept returning false no matter what I tried
It’s so frustrating!! my experience relied a lot on emotes, so I’m not sure what else to do other than create a gui with buttons to temporarily to play them.
I’ve just released an update cause I managed to understand how the default animation script was handling emotes (It was using the PlayEmote BindableEvent BindableFunction), and testing custom emotes in Studio seems to be working correctly for me
I’ve just tested it, I still seem to have the “You do not own this emote” error in the chat even though it’s a custom animation, I’ve set the id in the script, am I setting it up wrong? Sorry for bothering you.
just added the “bk” as a test
when I type “/e bk” in the chat
I understand the issue much better now, but unfortunately this is a situation where trying to fix this issue is creating a new problem
As I previously mentioned (and I learned today while trying to fix this issue), the default animation script uses a BindableFunction to handle emotes. The BindableFunction seems to be invoked from a core script, so I won’t be able to make any changes there. The script that’s invoking the BindableFunction passes either a string, or an animation, as an argument. It passes a string when you use one of the “regular” emotes, and an animation when you use one of the emotes you have equipped to your character
I tried handling emote command logic myself, which worked when playing the “regular” emotes, but kept giving me that error when I tried playing the equipped emotes, and the only solution I found to avoid that error is to use the BindableFunction, which unfortunately displays the “You do not own that emote” warning when you try to play a custom emote
Essentially, I don’t think there’s currently a way to handle “regular”, equipped, and custom emotes combined at the moment, without some kind of error or warning showing up
This version might allow you to use your custom emotes, and it also supports the “regular” emotes, but doesn’t support equipped emotes:

Ahh you didn’t have to do that, it worked like charm, thank you ever so much!!!
Hey i am currently using this, and it does not seem to be working, i assume i have done something wrong, Animations are not playing at ALL
It’s quite late where I live at the moment, so I won’t be able to help you until tomorrow
It needs to be named Animate in-order to replace the default animation script, and make sure that it’s a direct child of StarterCharacterScripts, not StarterPlayerScripts or somewhere else
If you’ve made any changes to it, you can try reimporting it from the marketplace
Well, here is the issue aha, i’m respecting all the requirements in order for it to work as it should but turns out it does not. the animations are not loading at all, im just a brick walking
Are there any errors showing up in the output?
If you replaced the default animation IDs with your own, make sure that the animations were published under the same person or group that owns the game, otherwise they’ll fail to load
I also recommend temporarily disabling any other scripts which are handling the player’s animations, if you have any, as one of them could be blocking Animate 2 from running correctly
Also make sure that you don’t have any plugins running which edit the source code of scripts, as they could be accidentally breaking it
One last recommendation: If you have set Workspace’s SandboxedInstanceMode to Experimental, you’ll need to set Animate 2’s permissions in-order for it to be able to work
What’s wrong with the default one?
i think its because of that, it cant be because of custom animation ids i don’t have custom ones i just plugged and play
this looks really interesting! are you planning on adding staging animations to it?
In that case, make sure that the script’s Sandboxed property is disabled/false
If the script doesn’t have a property named Sandboxed, then SandboxedInstanceMode isn’t enabled, so the cause of the issue is something else
Does Animate 2 work if you test it in a different experience, or a new baseplate?
Another question, just to confirm: Are you using Animate 2 for player controlled characters, or for NPCs? You’ll need to copy and paste its code to a server Script with it’s RunContext set to Client if you want to use it for NPCs (also make sure to add a BindableFunction named PlayEmote as a direct child of the script, otherwise WaitForChild will yield indefinitely (or you could delete the line that’s waiting for it, if you prefer))
