Numbers Collaboration - offline all the time
Running into a persistent problem with Numbers on macOS Sonoma. I have several Numbers spreadsheets saved in a shared iCloud Drive folder that's accessible by three users. For whatever reason, on my account (the primary account for family share) when editing spreadsheets in the Numbers app on my 13" MacBook Pro M2, Mac mini M2 Pro or iPad mini 6, Numbers will tell me that my changes are not being uploaded because Numbers is 'offline'. This problem has persisted across multiple macOS/iPadOS updates and multiple Numbers updates on all three devices. I can access the files without difficulty in the iCloud Web version of Numbers without difficulty, but essentially can't use the thick clients. Any edited files will show up in the Numbers 'sync status' screen as 'Syncing with iCloud' with a spinning ring basically forever. Strangely, when I load the files on the computer after making changes in the web app, the changes show up on the computer, indicating that iCloud is at least partially working. All three devices are on the current versions of macOS/iPadOS/Numbers.
What I've tried so far, without success:
- Disabled Advanced Data Protection
- Disabled iCloud relay
- Logged out of iCloud and logged back in on one device
- Logged out of iCloud on all devices, then logged back in on one device
- Logged out of iCloud on the Mac mini, deleted the user account from the Mac mini, then re-created the user account on the Mac mini and re-connected to iCloud
Looking for any suggestions folks may have before I open a ticket with Apple Support. Ideas like 'delete your Apple account and create a new one' are non-starters, as it is the main account for a family share with five other users on it and I'm not dealing with that mess.
