Syncthing freezes mid-sync while trying to sync my music folder between my Fedora 37 desktop and Android 13. The other folders work perfectly fine. Restarting Syncthing does nothing and I am on the latest version from F-Droid. The music is synced to /Internal storage/Music/Music on my phone. I’m also on a university network if that matters.
Syncthing is able to sync any file/folder name depending on what the destination allows.
Colons in filenames and folders are allowed by Linux and Android, but for compatibility reasons Android follows the same restrictions found in Windows.
