Additional context

If a request could be made in this report, it's an option to have error reports sent to you automatically rather than go through all these troublesome things. Essentially an automatic crash/error report. Would probably end almost all problems for good if issues are addressed quickly since most who use an app would never report any issues when they arise, preferring to simply leave/uninstall.

NicoNico is applying encryption to live streams, which makes our app unable to play them.

We have to wait until the community find a way to decrypt them, see yt-dlp/yt-dlp#12365

[InfinityLoop1308]

For your suggestion, the problem is F-Droid doesn't allow apps to report anything automatically, so that's the best we can do.
