@mase idk, can you send a yt-link please, so I can test it?
@dennix It is every yt link.
With the app you can watch peertube videos inside the app. Just click on this link
Change resolution: ok
Skip back/forward: ok
I can't say it's not a Mastalab bug without deeper investigations :)
I am surprised that it doesn't work on a recent device.
You can play them with other browsers installed on your device without GP services, so it doesn't come from here.
Also, you can play peertube videos without any issues.
Could you try to use your favorite browser in incognito mode with yt, Mastalab built-in browser works like that.
You might have issues on older devices. I will try to fix that.
@tom79 I have a XperiaX with Omnirom 8.1.0. But the issue seems to be with Youtube only.
