Thanks for checking that out - I did get it working but in a roundabout way.
- I couldn’t run a backup as clicking on the Backups icon in the preferences window doesn’t change anything for me (actually none of them are selectable, just the General pane) but I went ahead anyway.
- Quit Drafts.
- Deleted the
~/Library/Group Containers/GTFQ98J4YG.com.agiletortoise.Drafts folder fine - there was also a Drafts-Dev one which I left alone.
- Could not see any folder
~/Library/Containers/com.agiletortoise.Drafts-OSX in the Finder at all. However, when I went in the Terminal and checked, there were quite a few folders with “agiletortoise” in them, so I moved them all out.
When I restarted Drafts, it didn’t initially sync anything from iCloud, but when I went to the preference window - which now had all tabs available - then clicked iCloud > Reset Sync State, everything appeared again. The service seems to be working fine now as well.
