Crash on Android 10 while syncing an folder

[Paule89DE]

Error syncing folder with mobile. I think caused by special bars on filename.

Problem caused on try sync an 700mb mp3 folder. File list can be requested by message.

• sorry I am new on github, I hope this Informations can help you to debug our app.
