FaceTime Mac issue (Unknown Caller) when FaceTime iPhone shows user names
I'm currently running macOS X Catalina 10.15.3 on my 27" 2012 iMac. I also have an iPhone 6s running iOS 13.3.1. I've received a number of FaceTime-supported calls and video chats dating back to January. Normally it would sync the caller ID info. from my iPhone to the Mac and vice-versa when retrieving these calls/chats.
A few weeks back the entire list changed to show nothing but "Unknown" for EVERY caller on my iMac whereas FaceTime on the phone shows that some of the users are people that I do indeed know and that are indeed people on my contacts list (the actual videos or calls coincide with the date/time of each call). There are however a lot of calls from people that aren't showing up on my iPhone that show up on my iMac's list.
I also have noticed that my iMac hasn't been able to retrieve/answer phone calls made to my iPhone like it used to (this has broken off/on in the past based on macOS vs. iOS system updates, i.e. if both machines weren't on the latest version of the OS [which sometimes because of software incompatibility I've lagged behind on updating macOS to the latest version because certain applications aren't Cocoa64 native and probably won't be updated, or like Adobe which had issues for awhile with Creative Cloud and Catalina).
Is this a known bug or is there some suggested fix?
Examples:
macOS FaceTime:
iOS FaceTime:
Any help would be appreciated!
