It’s not letting me authenticate Paypal

Hi, I am having trouble getting it to verify my PayPal so I can take payments. Can you please advise? Thank you!!

We would like to apologize for any inconvenience. Were you having issues just by entering your PayPal account (email address) when integrating? Or, when you are already submitting the form to take payments?

May we know what exactly is the issue you are having, please? Is there any error message?

Please make sure also that the Sandbox Mode option of your PayPal payment field is disabled if you are using a Live PayPal Merchant account, not a sandbox account.
