CB 2107 - Wsus - 'Sync failed: Some Office updates not synced due to content download issue.'

Has anybody come across this issue?

Issue appears to have started after CB 2107 upgrade. I cleared .tmp files under c:\windows\temp, but the issue remains. Seeing multiple reports on the internet. Example - https://www.reddit.com/r/SCCM/comments/q76um1/sup_sync_error_due_to_o365_file_manifest_failure/
