Error when loading score to songbook
I get an error message when loading a song into the songbook of the Musescore app (Android 9).
Error on open file
Cannot read property 'isOffline' of undefined
The app crashes. After the restart, the song is in the songbook, but the song has the same name as the previous song. The song cannot be renamed.
