Apple Watch App - can't install via Apple's Family Sharing
I have a prepaid phone and truPhone cellular plan for my Apple Watch 7 Cellular which has a different phone number. I am using Family Sharing - with a fake child account (no idea why Apple does not allow me to add a adult account).
I can install other apps on my Apple Watch via App Store on the Apple Watch.
When I try to install Simplisafe App - it says "View" and "Requires Iphone". It does not let me install the app.
How do I install the app - or is there a way to get notifications with a 2nd phone number?
My phone is using my main icloud account - and my watch is using a 2nd icloud account.
I used the Simplisafe App on a non-cellular Apple Watch plan and it was terrible (never showed correct status) but I still need at least notifications.
