Add to Group not working in Catalina. My less important MBP is on Catalina and I just tried to drag a contact into a group. Nothing happened. It was a new contact added via my phone. Went to my iMac on Mojave and it worked. Click and drag the contact to the group and it went and shows up on MBP.
I had first searched to make sure I wasn’t having brain fade on how to do it. I wasn’t. https://support.apple.com/guide/contacts/add-or-remove-contacts-from-a-group-adrbbb1811b7/mac
Ah the clarity that happens when you hit the post button. I quit and relaunched Contacts and now adding to Group works on Catalina. Still a concern. Waiting for at least .1 on the iMac.
