I am attempting to purchase a In App Purchase using my test account. I go to settings > Store and login via my test account.
I went through the process of adding credit card, etc. I go into app and click purchase and get this "Verification Required" screen (as pictured). I click continue and it appears to open a browser page. It comes up with "Sign In required" (as pictured). I click continue and put in password and click OK, after 5 seconds are Loading..... I get "Sign in Required" again (as pictured).
I am unable to test my app and my in app purchases because it refuses to allow me to sign in and verify my info it appears.
What to do?!?
p.s. - This account works fine in app store, I'm able to purchase apps, etc. Only time this verification thing happens in my sandbox / test app where I'm trying to purchase (test purchase) my in app purchase. My account IS signed up under my Apple Developer account under In App Purchase Test User.
