App not showing system that's already set up

@davey_d​

I am having the same problem--also on iOS 15.2.1.  The problem has nothing to do with trying to login to two accounts at once.  I can login to a second account from the app and can see the basic account information.  However, the app does not see the installed SimpliSafe system.  It opens to this screen:

Welcome to SimpliSafe 

Let's set up your security system now. 

<Set up System Button>

If you press the button it asks you to enter the site name and continue with the initial setup.

The system itself is still working fine.  I confirmed that test signals are being received and the history and configuration all look fine if I login to the account from a desktop browser.  However, the app on the phone doesn't think there is a system installed on this account.
