Screen Time App Limits Not Working in Catalina
My son has a 2012 MacBook Pro running macOS 10.15.3. I recently upgraded the HDD to an SSD, and the app limits were working prior to that. But, I don't know exactly when they stopped working...because he didn't tell me. So I don't know if it's some account transfer issue with the cloned drive, or if something broke in a Catalina update somewhere along the line.
The problem: The app limits simply do not work on his MBP. Downtime, though, is still functional. Screen Time is also functioning perfectly well on his other devices (iPad and iPhone). So, his Apple ID and our family sharing account is set up correctly.
The machine has been rebooted several times with no effect. I've tried editing the existing limits and adding new limits with no effect. I do need to try signing him out and back in, but I don't have his phone right now to verify the sign in. Should that fail to fix the problem, what else can I try?
