Pro version's Offline mode

Pro version offline mode.

I’ve got simiar problem to this guy: Can’t get courses offline and this guy: Offline pro version not working
I might start to see a pattern here?

I already wrote 2 bug reports and got 2 replies telling me to reinstall Memrise app(2 when not counting in automatic replies, 4 in total).
WELL THANK YOU MEMRISE STAFF! I WOULD TOTALLY WRITE SECOND TICKET IF THE FIRST ONE SOLVED MY ISSUE RIGHT AWAY!
I wasn’t sure whether my account activation didn’t go through so I installed android on VM(rotation doesn’t work on log in screen, fix that aswell) downloaded Memrise app and voila… It worked! Offline mode all the way!

What am I trying to accomplish here:
If anyone has got enough knowledge of Android filesystem and tells me which Memrise files to transfer from VM drive to Android phone(non-rootable, sadly) or if some guy from Memrise developement team sees this and either changes download system to work on older android phones(4.4 isn’t that old anyway) or makes an option within app to select file with already downloaded course.

Note: Tried to copy some folders along the lines of com.memrise.offline_ and com.memrise.cache and merge them with similiarly named folders on my phone with no success.

Offline mode doesn’t work on android 4.4? I see no reason why it wouldn’t. I don’t think you’re going to get any help if that is the case.

I see no reason it shouldn’t be working aswell. That is why I went here to look whether someone had similiar issue and if they found a way to fix it. Didn’t find anyone that found a solution to this on his own, so I wrote this post.

I also suggested an option to this that would be universal for everyone across android platform, not so hard to implement by devs and easy to secure(check login status when mounting offline files).
