Settings are not saved and the custom skin is black

HTC 10

Hi,
When I open MC:PE, all the settings, servers etc that I previously made changes to are reset and it's like the first time I open the game (promt to sign in with xBox...). Also, when I try to have a custom skin, it looks completely black.
This issue only occurs when MC:PE is on the SD Card and it can be resolved by moving it from SD Card to Internal Storage.
I think this happens because in Andoid N (and Android M too), the SD Card is sort of encrypted: https://nelenkov.blogspot.com/2015/06/decrypting-android-m-adopted-storage.html
Hope this is fixed soon
