Ionic 6 app version was rejected - Guideline 2.1

I deployed my application play store seamlessly. However, when I tried to deploye it to App Store, the application was rejected and I received the following message. Guideline 2.1 - Performance - App Completeness although it works fine in simulator:

We discovered one or more bugs in your app.

Specifically, your app failed to load content after launch, only displaying a white blank page.

Please review the details below and complete the next steps.

Review device details:

  • Device type: iPhone and iPad

Please advise

I would try verify it works on 16.5 and look at dev tools in Safari to see if there are any JS errors.

Thanks for answer @twestrick,
I performed these steps but don’t see something in console:

  1. Choose iPhone 14 plus in xcode
  2. The simulator was opened (in the header I see iPhone plus 14 plus IOS 16.1) and the app works as expected.
  3. I opened safari browser and opened web inspector but I don’t see any errors or my http requests in network tab.
    maybe I"m missing something in debug process.
    could you please provide more details?
