Workaround
Exit the undefined page and go to the DevForum. Click the Blue login button on the top right of the screen and you should automatically log in.
Extra Note: This does not apply to the Discourse App. It will only work when you use the website method.

Can confirm that this has indeed been happening a lot lately, I’m on mobile and using safari, but this “bug” happens on both chrome and safari to my knowledge.
Also I don’t have any browser extensions installed
Can you provide a screenshot of network console and see if there are any HTTP 4xx or HTTP 5xx errors from any endpoint on apis.roblox.com/application-authorization ... ? (You can send it as a private message if you want)
Does this happen with all your accounts, or only specific ones?
The issue is related to the 2SV/2FA prompt not respecting the redirect in the URL properly, which is why I couldn’t repro it before since I’m within the 30 day threshold since last time I went through 2FA. I’ll get this investigated!
The bug has been fixed! You will now be redirected to the DevForum instead of the undefined page when you have 2FA on. Thank you for getting this fixed sir.
