I have a 14 Pro Max. It has mostly been a good phone but it has had consistent connectivity issues when switching from wifi to cellular. Back when I was on 6.0.3, I would actually have to reboot the phone. My solution was to just leave the phone on cell data. Now I am on the latest and while things seem somewhat better, I am still having connection issues. When I leave my house, sometimes the phone will hook right up to cell and sometimes I have to turn it on for a couple of minutes to get it to connect. Today I was trying to send a message and it took three tries before it hooked up. I am on the latest iOS and my phone is on T-Mobile. Is anyone else having issues? I guess I will go back to leaving the phone connected to cellular.
