Att Hotspot Disconnecting ievice
I have an ATT account for the hotspot in my Ford truck. Before the IOS 16 update my iDevice would connect and stay connected to the mobile service in my truck. Since the update I must manually connect to the service. A minute or two after the device locks the connection is lost and I must again manually connect. It will stay connected as long as I am using the device.
I called Ford they said the issue was with ATT. I called ATT and went through the steps they tried which amounted to reauthorizing the hotspot. They then said advanced support would call me back in one hour. It has been 72+ hrs and no response and not fix.
