Contacts app question

Go to System Preferences, iCloud, and UNCHECK item Contacts,

Close system preferences, open it again, and CHECK item Contacts again

this should solve the problem

If it doesn't, Sing Out of iCloud on Catalina, and sign in again

I upgraded to Catalina on my MacBook and now I cannot add any new information to contacts app. However, I can on my iPhone. What's going on?

Did you try rebooting and try again?

I have the same issue
