kasper, So, #Youtube changed something (again) on their part and now #Invidious – a front-end for Youtube without tracking and advertising – (again) cannot play their videos.
Error message: “The video returned by YouTube isn't the requested one. (Android client) (VideoNotAvailableException)”
Bug report: https://github.com/iv-org/invidious/issues/4498
So far, the other alternative front-end #Piped as well as the Android app #NewPipe still seem to work.
