People cannot pay in Store

Hi everyone,
I am experiencing problem that almost every single client is unable to pay.
What happens is once they click Pay, they need to provide address and region.
And when they do that, going to next step they always get message:
“Sorry our products are not currently available in your region”

The regions are set how they should and they are all activated on Shipping settings, but still every client gets same error.

Anyone can assist me since Wix does not have proper support email or chat

The “proper” support is Wix Customer Care , and they can help you with site and system issues.

Apologies for that. Didn’t checked well enough that there is chat.
Thanks

I’m having this problem and Wix isn’t resolving it, have you had any success?
