Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
I'm in the same boat. It stopped working for me a couple of days ago. I left it on the loading screen for a while and it suddenly loaded (although my channel feed was wonky). I tried it again tonight and so far no luck. It's stuck on the loading screen.
I have the exact same issue. Unfortunately TTV app stutters with all streams. Many users have reported the issues to the dev in the TTVStream Discord. Hopefully he can fix it soon. The legacy Twitch app was supposed to be shut down in September 2019 but didnt. I fear it may be the end now. I had to switch to my FireStick until or unless the legacy app or TTV app are fixed and usable.
I wanted to come back in and say the dev for the TTV roku app is really amazing. He is helping users and constantly working on tweaking the app. The stuttering issue is still being looked at but has cleared up for me. It's a great alternative to the legacy Twitch app if anyone wants to check it out.
Mine not working either. I uninstalled it and i re-installed it worked for like 1 minute then when u go back to home screen and launch the app it gets stuck in loading screen again. So R.I.P. roku. I will be switching to a platform that has twitch (Amazon fire stick). Goodbye!
