Time Machine not showing older backups..
I have a WD Mycloud 4tb running as my Time Machine via Wifi. Backups were fine but after I upgraded my MacBook Pro (15" 2019 8 Core) to Catalina it's only showing 2 days (today and yesterday) worth of backups. (The Mycloud is telling me my oldest backup is Aug 2020.) I have reset the Mycloud, I have reset the wifi connection, but no luck. Any ideas what to try next? Thanks.
