My biggest problems with Tidal (except for the price) are: - Music suddenly becomes unavailable (greyed out), only to be become available under the same name later again (but you need to manually re-add it to playlists). - Sometimes it just stops the playback and if i resume it always jumps to one specific song.

I cannot say anything about the mobile player, as i only use it on PC.

Alternativly: Just buy the music you like as FLAC.
