Recently updated my app so that it can view V.24 folios. I just updated that part and didn't change anything else. I submitted it to Apple and it was rejected for the following reason:
User is unable to sign up for Free Subscription. When the user taps "Subscribe" button, an activity indicator spins on the top of the screen with a text stating "Purchasing subscription...". However, after approximately 30-40 seconds later, an activity indicator disappears and no further action occurs.
Any ideas on what I need to do?
EDIT: Ok so I went through the App Builder again and noticed that under the "Free Subscription Product ID" I had put in the number for the Apple ID. I changed it to the "Product ID" under the free subscription in my in-app purchase. I'm guessing this will fix the problem?
Yes, you need to include the 'Free Subscription' product id in DPS App builder, thus rebuild your app and resubmit the app for approval.
