The Beta 2 update caused a lot of internet issues.
The phone shows full bars, but the 5G or LTE icon disappears and the internet connection doesn't work.
The only fix I have now is either to stay on WIFI or turn on and off airplane Mode to reset the connection.
The random Internet dropping happens multiple times a day.
I've had a couple of instances where I've had zero internet connectivity with full bars on 5G. hasn't happened enough to completely knock me off balance, but it was a problem when it did.
