Onyx BOOX MAX 2 Configuration issues

Hi guys,

I got new MAX 2 device yesterday and as for me it is really good: big screen, light weigh, fast, Android 6.0.
Only critical issue I faced was battery drained in a few minutes using Wifi while downloading book from Internet via stock Browser (I believe it will be fixed soon in update). I transferred my books over USB instead.

During configuration I was stuck with following:

- How to install additional fonts, like Bookerly and Literata. I was trying to search on e-reader and other places how to do that and ended up that it would require rooting to install new font. My only goal (at least for now) is to make it available in stock reading app (NeoReader if I'm not wrong) and I didn't find any way to do it without rooting.

Could some one point me what I missed in that and/or way to solve it?

Thanks!
