Mav 2 pro not connecting

We have a Mavic 2 Pro that is not connecting to DD. Our old tablet aged out of DD, or so I thought, the it would not connect to the Mav 2 Pro. Got new tablets, Samsung s9 FE’s, and have same problem. See all the things I would expect from DD but it is not connecting to the drone. Anyone having similar issues? Thanks

Oh, we are running 5.37.0 DD and my firmware on the Mav 2 was updated within the last month to latest. Sorry I don’t have that version off hand.
