So I switched to #kdeconnect and #gsconnect for syncing stuff to my #android phone. Actually this quite nice with some minor hickups.

But ... the phone is mounted automatically to via ftp. You have to add /storage/emulated/0/Documents to the mount for modern androidos.

But then I can easy sync stuff if rsync, because I can access over the terminal via /run/user/1000/gvfs/sftp:host=IPADRESS,port=1739/storage/emulated/0/

Don't we just love #linux for this stuff....
