I upgraded to a new phone recently and installed the version of the game that's meant for newer devices. (My old device was an LG G7). The device I have now is an LG V60 dual screen. I managed to play the routes for Markus and Heath completely through, but when I tried to start Randal's route, it requested that I buy the full game again even though I've already bought it. 

However, at least this time I can make it through two routes before this happens. When I had this game on my LG G7, it had this problem right after finishing the first route. 

I really hope there's a way to fix this.  I doubt I'll be able to unlock all of the chapters since this keeps happening. Q.Q 

Thank you for any help or advice.

Actually nevermind. My husband figured out how to fix it. I'll just have to put the save files aside when reinstalling, then replace them back into the folder so I don't lose any data. Thanks argent games.

Hi did you turn off the auto-updates on play store ? If not i recommend you do it (because the play store update the game and it go back to the free censored version)
