Why am I experiencing a failure of upload from iMac of photos library. Failure of sync across all devices, including iPhone 11 Pro, iPad Pro 10.5” and Macbook Air 13” late 2020. Same iCloud ID on all, all preferences set to iCloud Photos “On”. All on same wifi router. All software updated to latest version.
