Apple One Premier on MacOS Catalina
I currently have four family members with iphones on iOS14, iPads on iPadOS 14 and Macs on Catalina (not BigSur). We subscribe and family share Arcade, TV and News.
I wanted to upgrade to Apple One Premier today and the Apple website said I needed a Mac with BigSur or iOS/iPadOS 14 to initiate the upgrade. I contacted Apple support and asked if that meant that upgrading via iOS or iPadOS 14 would cause all our Macs (Catalina) to lose access to all of our Apple services until we upgrade to BigSur. The support person told me that is correct!
Can this possibly be true, that no services will work with Catalina Macs if you upgrade to Apple One?
I'm asking here because it doesn't seem that this can be correct info.
