Frustrated with RBR50/RBS20 /RBS50 ORBI and the app

I'm so frustrated with this router and the app. It is extremely flaky and somewhat unstable.  I frequently drop wifi/internet, almost as if the router reboots.  Devices don't always show up in the app.  I'm running the latest firmware (2.7.2.104) and from the numberous posts I read it seems that the only way to restore functionality (like getting all the conencted devices showing up ) is to reset to factory defaults and start again.  Which means that I lose all my work in naming the various devices in th app.  I can't sort by IP or MAC address to find an unknown device which is also extremely frustrating.  The app is currently showing 3 devices conencted... yes 3... I have about 40.  Im starting to think I made a mistake spending the money I did on the Orbi system (it was NOT cheap).  When is Netgear going to get on the ball and deliver some software and firmware that actually works?
