I love your comic and I want to give you a friendly heads up; European customers are getting their accounts flagged as fraudulent transactions when purchasing effectively anything via itch.io which is unfortunate so customers that buy this comic from you might get a text from their bank.
I just want to assure readers that it ISN'T the artist's fault that this is happening; itch.io simply doesn't have a European base of operations so when it takes money from your account it triggers this false-flag.
