I have IAP working for DAILY PASS in Fire App but I cannot get subscription to work. I followed the instructions for setting IAP up from here:
I checked my Subscription SKU and everything is correct. The issue is when I click GO PREMIUM, it says thank you, your purchase is complete. I click OK and it changes the GO PREMIUM button to WATCH NOW for my content. I click WATCH NOW and it says Purchase Error, your subscription has expired. Then GO PREMIUM button appears again. If I click GO PREMIUM again, it says I cannot complete purchase because last purchase is unfulfilled.
I checked Amazon App Tester and the transaction for subscription is there with a receipt ID, etc.
Can someone please help me? What could be causing the subscription to expire right after purchase? How can I debug this to see if it's logging any errors? I'm going crazy trying to figure this out. :(
