I am trying to buy a license of Superboundary. When I click the submit order button, I get, "We're sorry, your session has expired. Please go back to the vendor website and place your order again."
I have tried about a dozen times, on Chrome, Firefox, Edge, Safari, Android, IOS.
I have contacted the vendor 2checkout, I have emailed Alexey, sent message through website.
What can I do?
