Fix your platform
Your mobile app will be frozen on a single image, take multiple minute to load, play 3 seconds of the stream, then play a full volume ad, then go back to buffer for minutes, and repeat. Please fix this, YouTube streaming is better than this.
Also, getting a Picture in Picture ad followed by fullscreen ads made me literally turn off twitch. Because it was so irritating, it completely ruined the experience of watching the streamer.
This seems like an issue better resolved by our Support team.
