If you want to purchase the magical milestones key, it's better to turn on the gem/coins no cost and not consumed hacks, and then buying the gem version of the key (as this will cost you nothing).I am new to this sight and MODS in general but I was wondering on what people do for events like magical milestones were to be able to get the extra books and outfit you need the key, I'm asking because I've tried a few times to purchase the key even with all the MODS switched off it still says that this version of the game prohibits purchases of this manner, so back to the point I was wondering what people have done to work around this problem.
Many thanks for reading and I hope to hear back from someone :)
As for the purchases being prohibited, that could be due to you using the signed version of the apk (I don't think that it can interact with the play store). I have spent money on the game before, though I didn't use the modded apk to do so. Instead I have my modded game on my pc, and logged into a non-modded install on my mobile to make purchases.
