I had tried to Purchase Pro version on the 29th added to cart then i clicked checkout takes me to paypal login i login agree and then it loops back to page with check out button in which takes you to paypal login again ? I had sent email to Billing after i tried to purchase No reply . Sent 2nd email to billing No reply.
Paypal was experiencing some issues on the 29th and i am wondering if that is the reason, we have had the cart tested and it is working as expected. If you could please try again and if you have any further issues please let us know or send some screenshots and we can check it further.
