Disappointed newbie (multiple sensor error issue)

Installed SS three days ago, and already discovering that SS isn’t living up to the hype.

Aside from the one intermittently offline entry sensor, I just discovered, and confirmed w tech support, that the key pad information as to what entry sensors are open is incomplete.

Currently, the key pad reports 2 open sensors while the app - ios and web - shows 8 open and one offline.

Does anyone have any words of wisdom of how to deal w the discrepancy, keeping in mind that not everyone that arms and disarms the system has access to the app.
