I have a Pixel Pro7. Recently, I am unable to connect to the cameras of my security system when using data or work Wi-Fi. This has never been a problem in the past. Everything works fine from Wi-Fi at home. I get the alerts when away from home. Vivint says the system is good but wants to sell an upgrade. Verizon says everything is fine but wants to sell me a home equipment repair package. Anyone experience this? An upgrade mess something up?
