Ditto To everything everyone above has said, only difference is i tried 4 ways, hoping now i don't have 4 payments in waiting, a possible issue is my bank needs a verification code and affinity payment process does not have this at any step of the process and quite likely why it wont accept, this may be the same issue for others, paypal sounds like a bit of hit n miss too but we don't all have paypal to use anyhow, so thats not a good solution to offer.
Since affinity/serif has a lot of folks calling out about this with no help or solutions, and it seems it there was a similar issue back in 2020 and 2021, and that ive had no other transaction issues, plus the many different banks people are with, I'm going to highly doubt its my bank, i think we need some upper hierarchy on this and fast.
Affinity you have worked uber hard to bring us this software from day one, don't let yourself and your customers down now.
Sincerely hoping i get the Discounted price i tried for in the next day or so, i would dearly love to brag about my V2 suite.
