Samsung Smart TV QLED 2022 55inch - not fully compatible with Uverse equipment.

Uverse equip does not work properly with this TV -  a variety of tech's changing out all the equipment have not been able to fully get Uverse to work - latest problem is screen freezes for a few seconds - there's no pattern, it might happen 5 times in 5 minutes or may not happen for 1/2 an hour.  Only seems to start happening when Uverse TV has been on for several hours.  Also, error msg will sometimes appear when TV 1st turned - but disappears so quickly it can be fully read.  Just a lot of little things, like rebooting out of no where.
