@Farhan-Occess24 i faced too but only for facebook(for me facebook in mobile mode not working at all and this is looks like webview issue, but i think it should be investigated), but all another sites work well, could you provide more info? What unsupported video format? where is not videos undetected in mobile mode? and what android version?

@Farhan-Occess24 I fully reproduce your issue for facebook(facebook just start loading in mobile mode, before it did't loaded) But video detection not working for facebook in mobile mode, i got error same as yt-dlp opened issue, all you need is just wait when it will be fixed(in app youtube-dlp library auto updating on start) if you want you could try to change youtube-dlp library update branch from YoutubeDL.UpdateChannel.MASTER to YoutubeDL.UpdateChannel.NIGHTLY in DLApplication class, updateYoutubeDL method
