Smart View not working

AC Question

So as of last week my Samsung Galaxy Tab S2 model SM-T710 can no longer mirror to my UE48JS8500T. The tv goes to connect but then says Tab S2 has disconnected. They worked perfectly for the past year. The tablet is on 6.0.1 and the tv is using 1480.4.
I've done a factory reset and no luck...any suggestions welcome!
