In-App Purchase works in Sandbox & TestFlight, but App Review reports “No action on Subscribe button”

Hello everyone, I’m facing a persistent App Store rejection under Guideline 2.1(b) – App Completeness, related to In-App Purchases, and I’m unable to reproduce the issue on my end.

Issue reported by Apple Review Apple Review team reports: “No action occurred when we attempted to buy the subscription.”

  • Device: iPad Air 11-inch (M3)
  • OS: iPadOS 26.4.1

What I have verified from my side I have thoroughly tested the subscription flow under multiple scenarios:

  1. Sandbox Testing
  • Using sandbox test accounts
  • Product loads correctly
  • Purchase flow completes successfully
  • Apple payment sheet appears properly
  1. TestFlight Testing
  • Installed app via TestFlight
  • Logged in with real Apple ID (Beta tester)
  • Successfully completed subscription purchase
  1. Device Testing
  • Tested on multiple iPhones
  • Tested on iPad as well
  • Purchase flow works correctly on all devices

App Store Connect Configuration

  • Paid Apps Agreement → Active
  • Banking & Tax → Completed (no pending warnings)
  • In-App Purchase status → “In Review”
  • Product is correctly configured and attached to app

What Apple is experiencing Based on their feedback and screenshots:

  • Subscription screen loads correctly
  • Product price is visible
  • When tapping “Subscribe Now” → no action occurs
  • No error message, no purchase sheet

Is there a recommended workaround or reviewer instruction to avoid this deadlock?

Any insights or real-world experience would be greatly appreciated.

Thanks in advance.
