Not even speaking about all the ads in the default YouTube app without a subscription.
The app is basically useless in my opinion. It defaults to freaking 240p for every video. My phone is definitively not the problem, also not the Internet connection. Watching in Firefox on the same connection gives me normal expected quality.
This was better on some “feature phones” without touchscreen!!! YouTube app works and playback is in 720p / 1080p
I’ve given up YouTube almost entirely for PeerTube at this point. If I wasn’t to watch a video, I use the *built in grabber and it grabs the video. Then, I can always refer back to PT instead of YT.
