Hi there! I have an approved REST API app in my developer account which I want to now use on my production device to semi-integrate with my custom POS. I am following the instructions here: https://docs.clover.com/docs/private-apps to add the app to my merchant account, however anytime I follow the link, then select the merchant I want to add the app to, the page just loads non-stop and nothing ever happens after. What am I doing wrong?
