I have been using backblaze S3 (free 10GB) as my sync target for 6 months without issue. Using multiple Android, windows and linux clients. After I updated yesterday to:
Joplin 2.6.10 (prod, win32)
Client ID: 934a2e3ce27e4140b38601e1d3630c2d
Sync Version: 3
Profile Version: 41
Keychain Supported: YesRevision: 98fba37
I have not been able to sync. Checking Sync configuration hangs with "Checking... Please Wait" on every device. Has something changed? Is there a log to check?
