Can't connect new tablet

[speedycompton]

Been flying with my Note 8 works great but I decided I wanted a bigger screen so bought a Samsung Tab E and tablet holder. Installed DJI Go 4 app for Mavic. It won't link with tablet yet it knows it's there because it opens the app automatically when I connect controller and drone. Screen keeps popping up Enter aircraft. When I attempt that it opens the Go 4 screen and says disconnected. Also occasionally it say not connected to controller. Any help greatly appreciated.

Go into settings in go4 app on main page via cog wheel (think on the me screen) and turn on always connect via USB Debugging
Also on the Tablet activate Developer Options then go to Developer options and turn on USB debugging.

Also, if using the large (normal size) USB port on the rc, for the tablet, unplug the cord from the small USB port.
