Transfer Shared Albums in Photos
Recently added Catalina to my iMac on a partitioned IHD running Sierra. Transferred and/or updated programs including Photos, now running on either Sierra or Catalina. No problems EXCEPT the Photos program on Catalina does not have my Shared Albums from the Sierra Photos program. Otherwise everything else about Photos is OK.
BTW, the Photos on both Sierra and Catalina are in libraries on EHDs, and have been for years. The libraries are not on the IHDs.
What is the problem, and how can I fix it?
Thank you.
iMac 27″, macOS 10.15
