I've been trying to use PayPal for subscriptions on my website, and when I approve a subscription created with the subscriptions REST API everything goes as normal until I get to the end. After it's approved, PayPal shows me a page saying "Things don't appear to be working at the moment. Please try again later." instead of returning me to the return URL I set in the application settings. The subscription is completed though, I receive the webhook for the event and everything else seems to work fine. I've followed the subscriptions basic integration tutorial from the developer docs exactly and even after extensive searching I haven't found anyone who's had the same issue.
