Hi,
As Device is not Google services Certified, so no play store :( What I would suggest that you install https://www.amazon.com/gp/mas/get/android/ and then search+install MediaMonkey.

If that succeed then you should be able to buy MMA PRO too if you find need for it, but first make sure it runs and that you can install Latest Beta builds ☰ -> MMA Icon -> Register For Beta.

BTW WOW, that WAS one piece of expensive Tablet at 800+USD(800+EUR).

Has anyone run MMA on a paperwhite tablet, specifically an Onyx Boox like the Max3 13.3? A constellation of uses including long battery life and being easy on the eyes is leading me toward buying one. If MMA will run on it, that will be the icing on the cake.

I'm loving the idea of being able to see the screen all the time music is playing without plunging my battery into darkness.
