How to Fix Twitch?

I don't know it is happening only in my device or not. Twitch andriod app is acting weirder day by day.
Some Interfaces won't close when switched to full screen mode.
Full screen mode opens in zoomed mode.
pinch out won't work properly.
If I switch to another app and open this app it'll open in zoomed full screen.

If anyone know the solution for these problems let me know. I couldn't watch the Red bull matches properly because of this issue.

I also have a problem where my video gets desynced from the audio
The audio continues to play and the video gets paused for like 10 seconds at random

The only thing that works correctly on Twitch is the ads.
