I’ve noticed an issue where the default chat UI of TextChatService would flash white when it’s being opened on Mobile devices. This issue has been happening since a few weeks or up to 1-2 months or so now. This issue doesn’t seem to affect other platforms like Windows, and it only affects TextChatService.
Okay, after further testing, it seems that it also happen on Windows, but not consistently like in Mobile. It would always flash white for me when an experience or the chat initially loads for the first few seconds and often times when the chat box is opened after a while for it being closed.
