simplisafe app

Not getting chirp alerts from motion detection by outside cameras -- including doorbell cam -- perhaps since upgrading my iOS on iPhone SE 2020 to 6.1.1. Wife's iPhone 8 with iOS 5.7 has no problems.

Also, under General Settings of app at the bottom of the screen in a box, it says Replace Base Station. I have done all troubleshooting with SimpliSafe support, including power-cycle of base station. They insist my system shows fine on their end and that my SimpliSafe app is the current version. Maddening. Help, please!
