Unable to use PayPal Checkout app in app center - Business Sandbox

[Vanblerk1]

Hi,

I'm trying to access the PayPal Checkout section of the App Center on the business sandbox profile. When I navigate to App Center -> Accept Payments -> PayPal Checkout all I get is a never ending loading bar as can be seen in this screenshot:

 

 
From the logs I can only see the following (although I don't know if it is necessarily related to the issue):

 

What I've tried so far is:

• Clearing my cache and cookies - Was not successful (Suggested by PayPal technical support)
• Creating a new sandbox business account - was not successful

This is not happening to any of the other apps, i.e. Subscriptions, Invoicing, Recurring payments, etc. Only on the PayPal Checkout app.

Could it be a bug in the Sandbox environment? If so how would one report it?

Any help on resolving this would be greatly appreciated.
