The app seems to have associated itself with the wrong Google account on my phone. I can only guess that the now-deceased owner of the account played candy crush and the installation made an assumption. You'd think it would use whatever account was logged into the play store, or ask. Anyway, how do I get it associated with the correct account?
I only realized when I went to make a purchase and all the payment details were wrong, so I couldn't make a purchase. Maybe that's for the best, or maybe there's an easy fix.
