iCloud Drive documents do not sync from IOS device to iMac
Changes made to Numbers documents on the iPhone or iPad seem to sync to iCloud promptly, or at least the message "Synced with iCloud" appears on the screen after editing or moving a Numbers file. However, the change does NOT appear on the iMac. The IOS and macOS devices have iCloud Drive turned on for Documents and Desktop, and for all the Apple Apps including Numbers, and I am signed in on all devices. Changes made on the iMac sync promptly (the Cloud symbol disappears in Finder) and the change appears on the IOS device Files App and / or Numbers App in seconds, but NOT the other way round. Eg, edits made to a Numbers file on the iPhone do not appear in that file on the iMac. Similarly, a file moved (eg) from Desktop to a Documents folder on the iPhone still appears in the iMac desktop indefinitely. This seems to be broken. MacOS 13.4.1, IOS 16.5, iPadOS 16.5.
Anyone else experiencing this? Any solutions?
