Hi all,
Back from a short vacation, I once again tried to sync my Android devices (smartphone + tablet) with the original Joplin files on my OneDrive but to no avail: same error, Joplin only retrieves 1 notebook out of ~60. It seems that the mobile app is wrecked or maybe useless with some sync targets: can you please confirm? It's a pity as I move from Evernote to Joplin as Joplin would support all devices too, which is a requirement for me... 
Thanks in advance for any help!
