PayPal Checkout & PayPal Pro - stuck in loading screen

Hello,

The only PayPal gateway that will work is PayPal Pro using the API codes, although it won't accept credit card from my buyers.

If I try to connect my paypal account to other paypal gateway it will not connect. Generally it will log in and say return to jotform, and then get stuck in a loading screen for eternity. 

Hi there - Apologies for the inconvenience. 

Could you please try clearing your browser cache or use a different browser to check if it makes any difference?

I have also cleared your form cache from our end as a precaution.

Looking forward to your reply.
