Songs stop playing at start or end of song

[WouterHofman]

I use spotify family on xiaomi redmi 4 android phone. Dutch subscription living in China. Many songs (not all) stop playing in on or off line mode, extreme quality, on my downloaded songs, albums or playlists. Every time it happens i need to press 'next' (when stuck at end of the song) or touch the 'ball' that indicates the time in the song. This sometimes requires iterations.

Tried all tips to no avail: reinstall phone and app, play with cross fade, play songs first online, then in offline mode, close all other apps, get spotify out of the phone power saving mode, stop or untick all other settings in spotify.

Please help?!
