Initial Sync does not create Notebooks

Hello and Greetings,

I installed Joplin yesterday on my Mac (Version 1.0.227 ) @ home and importet stuff from various Evernote Notebooks. (approx 10 Notebooks) and synced it via OneDrive - everything fine.

Now I installed it on my work PC (Windows 1.0.227) and initiated the sync - Joplin downloaded all Notes but did not create the 10 Notebooks - I just see the Notes in all notes but they seem to be orphaned.

Any hints what was happening ?

Joplin 1.0.227 (prod, win32)

Client ID: c8d45a8dd7a447708bf51fc9a0f1584d
Sync Version: 1
Profile Version: 30
Keychain Supported: Yes

Revision:

I have the same problem between my Mac desktop and ipad. Unusable unless this is solved.
