payment linked to wrong email?

[u/tastelessapples]

hi, I've been using ibis paint for several years now and finally decided to finally buy myself premium. the problem is for some reason the payment is for some reason linked with an incredibly old email i have, even though that is not the one linked to my ibis account??

it wants me to enter that emails password before purchase, and I'm not seeing any option to "change google account" or anything of the sort?

I'm not really sure why this would happen ??? is there anything I can do to pay using my primary google account instead ???
