Guideline 2.1 - Performance - App Completeness

My app keeps getting rejected by Apple Review team.

This is their reason:

The app still exhibited one or more bugs that would negatively impact users.

Bug description: your app was unresponsive to scan provided code or barcode on website before we purchased the subscription.

Review device details:
- Device type: iPhone 13 mini and iPad Air (5th generation)
- OS version: iOS 18.5 and iPadOS 18.5

We have tried our own devices but it works fine for us. We aren't able to reproduce the issue. What should we do?

If your app has been rejected and you need help resolving the issue, consider taking advantage of one of the following support options available from App Review:

  • Reply to the message from App Review in App Store Connect and request clarification.
  • Request a call with an Apple representative to discuss the outcome of the review.
  • Submit an appeal to the App Review Board if you believe your app follows the App Review Guidelines.
