Currently, we are aware of and tracking an issue where some PayPal orders have a noticeable delay in processing. This has been identified by our web technicians due to an outage PayPal is experiencing at the moment.
More information can be found here: PayPal Incident Report
We advise holding off on placing payments with PayPal for now, and instead you can select Stripe as an alternative. In the meantime, please allow up to 72 hours of extra time for the payment to finish processing. If the order has not completed within that time frame submit a support ticket with a screenshot of the PayPal transaction ID for assistance.
