This is happening to me as well. Some streams completely freeze as soon as I try to type in chat or use emotes. Not all however, and not the same streams every time. I am not multitasking at the time. I have tried killing the app, restarting my phone, deleting and reinstalling the app. I just did the most recent update today and was hoping that would fix the issue. It did not. In fact, it was only happening for 1 streamer before, and now it's multiple. I have an iPhone 14 running on IOS 17.0.3
Thanks a lot for the info. Could you confirm which app version you're on so I can pass that data to the engineering team?
