Google One VPN Connection Issues

I’m on AT&T and kinda bummed their VPN randomly disconnects sometimes and wanted to try the Google One VPN and thought it doesn’t disconnect, there’s no connection sometimes. I have stopped the AT&T armor VPN. Do I need to uninstall that app for Google One to work? I believe it’s called App Armor. Thanks! I do have antivirus already. Thanks for any help!

The phone should only let you have one active VPN at a time.

I switch between Google VPN and ProtonVPN, but only one is active at a time & neither can interfere with the other.

The biggest thing to remember, is establish a solid data connection on the phone first, then engage the VPN.
I have some connectivity issues this way myself, especially indoors where 5G sucks balls (i have since disabled 5G on my phone, going LTE only).
If the baseline connection is poor, then enabling the VPN is just adding complications on top.

Thanks! I set it up now so that it works and only use the Google VPN. Much appreciated!
