Musescore app 2.8.2 does not work on any of my four Android devices

I have updated my Android devices to MuseScore 2.8.2.
It is possible to see my scores but when I choose one of them to play then MuseScore hangs for a long time before it show a message "This item is temporarily unavailable".
I have also uninstalled and reinstalled and still get the same error on all my four Android devices.
This is very annoying since I use MuseScore to practice choir singing preparing for a concert.
