I'm on 10.15.1. Find My will open but then tell me I need to login to iCloud. I am logged in and all of my other iCloud services are working. Photos, iMessage, FaceTime, etc... I've opened a ticket with Apple and sent logs. Today they wanted to record my screen. I found another person with the issue on the Apple Support Communities, but no traction. Has anyone else experienced this and found a way to fix it? Logging out of iCloud and back in doesn't work. Another user on the Mac Mini with their own iCloud account is able to launch the app with no problem.
