Shared Numbers spreadsheets not syncing
Tried asking this previously in the Numbers forum, but got no responses.
Running into a persistent problem with Numbers collaboration on macOS Sonoma. I have several Numbers spreadsheets in a shared iCloud Drive folder that's accessible by three users, each with a separate Apple account. For whatever reason, 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 on the Mac or iPad. Any edited files will show up in the Numbers 'sync status' screen as 'Syncing with iCloud' with a spinning ring basically forever. All three devices are on the current versions of macOS/iPadOS/Numbers. This problem affects all three users/iCloud accounts who have access to the shared iCloud Drive folder.
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.
