We have a brand new customer who installed our app and has been getting 401 errors since. They installed our app a while back, and today they re-installed our app. I was able to debug the error down to an Invalid Token.
They were able to run Register just fine so it must be something to do with their Token assignment to our App.
I've tested several other Clover units without an error. We have several other Merchants who are using the App as well.
Thank You, Carl
