I received a new QB33 card reader.  I have an Iphone 12 pro updated to most recent IOS.  I have goPayment 22.02.0-n.  I call tech support and got a bunch of poor reasons why it wasn't working...  My experience thus far has been:

Turn on card reader "Hello"

Open app and go to "connect new reader" --> "New card reader found" --> press "connect to reader" --> "connecting to reader" --> reader displays "connected" --> phone displays "can't connect to reader, make sure reader is compatible, then turn it off by holding down the power button. Then turn it on and try again"  --> press "ok" on phone --> reader displays "disconnected" --> no readers are registered in phone app. 

If I go to bluetooth on my phone I can see CHB808xxxxxxxxx and click on it to connect and it connects, but it doesn't really change anything in the app.  No reader ever registers as connected in the app and displays a battery percentage.
