So I finally got my app up and running to be tested on the iPhone to see whether or not the Game Center & IAP works.
I can't seem to authenticate to Game Center.
On the First Layout
"On start of Layout > Authenticate Game Center User"
On user Authenticated > "Hide Game Center Icon"
Yet the Game Center icon is still there.
As for the In App Purchase this is the events that I used
On the first Layout
"On start of Layout > Add product ID "BLAH BLAH BLAH"
Wait 3 seconds
Request store listing
This is the error that I am getting
But when I tested it nothing showed up. I've already signed in using my sandbox environment account which I added on iTunes Connect.
Is anyone else facing the same problem as me?
