THANK YOU FOR REACHING OUT!!!
Thats really weird... sadly that's a Patreon issue so we can't resolve it...
However, if you buy Smug Ai here on itch and show proof of purchase on our discord server, I can give you all the Patreon benefits! ':D
(join our discord server and go to our support channel and say that u purchased the 5$ tier thru "itch io" and I will ask you for proof of purchase in dms)
If you cannot use ur credit cards on itch io aswell... Im afraid ur cards are blocked.
Try to talk with ur bank and if the issue is resolved, try to purchase Smug Ai again, but thru Patreon.
I hope I helped ya!! ':D
