Out of curiosity, does anyone else get an excessive amount of payment declines with this module?

Specifically, I tend to get alot of declines with people trying to use visa debit cards or mastercard debit cards. Or is this just a quirk of how these types of "hybrid" cards just don't count as credit cards on Square's end?

I still regularly get declines from US-based customers using US-based credit cards who I then have to instruct to contact their CC issuer to allow international transactions, then after they do so, their cards work, but that's just a US CC issuer security measure that's been killing sales regularly.
