App won't work on my iPhone after installing the new module suggested by Simplisafe

I installed the new module Simplisafe suggested because the 2G cellular connection is going away per the Cell Companies. After I received it, installed it and all equipment works fine with the exception of being able to arm/disarm from the app. I called today into Tech Support and got a very rude lady who kept blaming it on my phone and was absolutely no help whatsoever.

I had already done all of the thing suggested by Simplsafe in terms of troubleshooting my equipment, deleting and reinstalling the app, and moving the base station. Nothing. So I called Tech Support whom was not supportive at all.

I explained to the Agent that people were complaining about the app and before I could finish she said "what people?" I told her the ones here on the forums. And she said she didn't know about that. So after trying to talk and her not letting me, I just hung up.

So I still don't have the app working, and it is something I pay/paid for and it seems there is no help from Customer Service. I have had this system for several years now and am very disappointed that the once great help you could receive is pretty much non existent. (I went through a similar issue via emal last year.)

I guess Simplisafe has gotten to big to help it's long time Customers and is more interested in selling equipment than supporting it.

Looks like I'll end up getting a Ring system that is cheaper and about 1/2 the price for monitorig.
