I have a problem with IOS in iPad running iOS 12.3.1 on Wi-Fi

When uploading my application to Apple Store Connect, I have sent the following error to solve:

Guideline 2.1 - Performance - App Completeness

We discovered one or more bugs in your app when reviewed on iPad running iOS 12.3.1 on Wi-Fi.

Specifically, no content loaded when we tapped on the following categories in the menu bar:

  • VIP list
  • Restaurants
  • Packs
  • Tickets

I need to resolve this issue, since in other devices it works but in Ipad iOS 12.3.1, it can be a compilation problem of Thunkable application.

How can I solve this problem in order to upload my application to Apple Store Connect?
