All web-related pages causing extreme lag in Roblox application only on iOS 12, 13, and 14. Major bug

This is a major bug. Every time I go to anything that is web-related (Like for example the Servers page on games, Profile, Communities, Inventory, Settings, Messages, Blog, etc) inside of the Roblox application it causes extreme lag, like I’m guessing 2 fps, and the only fix is to completely relaunch the entire app. Anything that isn’t web related runs completely smoothly like scrolling through experiences, changing avatar, playing experiences, etc.

I have tested this on iOS 13.4, iOS 14.3, and iOS 15.8.3. It does not happen on iOS 15 and above. I have seen a video of this happening on iOS 12 from someone else.

I don’t know how long this has been happening but it’s been happening for at least 4 months. I’m guessing anywhere from 4 months to a year.

Here is a video I made of it happening, the application running completely fine and smooth like 60 fps, then I go into Servers and the app becomes like 2 fps and completely unusable. It is only 28 seconds long so please watch it: https://youtu.be/nwNvL2URrek?feature=shared

Expected behavior

I expect web-related parts of the app to not cause this permanent lag that can only be fixed by relaunching the app. Like opening Servers on games should not cause the app to run at 2 fps where the only fix is to completely relaunch the entire app.

You’re welcome! This issue is definitely affecting many many devices, three entire versions of iOS/iPadOS. Even though these are older iOS/iPadOS versions, it’s a very big issue. You can’t use many parts of the application properly because of this.

Everything web-related causes extreme lag, making the app nearly unusable. If you need any other information just let me know.

This bug does not happen on iOS 14.8. Just tested on iOS 12.2, and it happens there.

We’ve tried reproducing the reported bug without success on our recent builds. We’re going to close this for now until there is new information to help us investigate this further.

This bug is still happening.

I will give you new specific information

My device: iPad 5th gen on iOS 13.4
Newest Roblox app version (As of now, it is 2.694.977)

This bug does not happen on newer iOS versions. Only iOS 13, and some older iOS 14 versions.

To reproduce:

  1. Test it on a real device running iOS 13. Preferably, use an iPad 5th gen, or something similar like an iPad 6, iPad 7, iPhone 6s, iPhone SE 1st gen, etc.
  2. Open the Roblox app
  3. Press the “More” button on the bottom right
  4. Press “Communities”
  5. Notice the entire app starts moving very very slowly and laggy (Around 2 FPS). This does not happen with the same iPad on newer iOS versions like iOS 15 and 16.

Video of me producing this: https://youtu.be/KlAlGCeCLWY?si=VRw0dTUH6wUXOAGH

In this video, you can see the app is moving smoothly, until I press the “Communities” button under “More”, then it gets extremely laggy.
