I have two sets of dev keys one for dev one for prod. I am in the process of getting my app approved. When I run the Dev keys I get to the app, when I use the prod keys I get a message that the app does not exist. So while in the process of getting the app approved WHICH KEYS AM I SUPPOSED TO USE for my app? It seems that they want me to use Prod keys, but when I try to use them I get nothing when testing this is what is confusing me.

Hello @preston86

When Testing the app for approval to be Published on the Marketplace, we test using the Production credentials. You should be able to accomplish testing with both dev or Prod credentials when using the Creators Zoom account, if you use an External Zoom Account you will get the error the app doesn’t exist, Please confirm.
