Have channels Dvr running on shield with hdhomerun 4k tuner. Works good except upstairs android tv (tcl). When I start up the tv, it tries to go to NBC as the default and then just spins at the bottom of the screen. Reset, turn off tv and back on, try everything and same thing. If I change the channel to another it does that slowly then I can go back to nbc. Any idea what the heck is going on?
Edit: I tried in on second TCL Android tv (built in) and it does the same thing.
