Can't connect w Kindle Fire HD (running Android 5.x)

I just installed Litchi for DJI on my phone and it appears to work. I then installed it (also from Google Play) on my Kindle Fire HD 8 (7th generation), which runs Android 5 (Fire OS Litchi opens OK on the Kindle and when I start the controller and the drone (Mini 2), things still look OK. But connecting the controller to the Kindle, it still says “Disconnected”. I tried a few times and the same result.
Any ideas on how to overcome this?

Oops, I had “Location based services” off. Turning them on, and now it connects. Later will try the Litchi functions.
