Black splash screen on iOS app

I built an iOS app and everything is perfect except launch screen.

I uploaded launch screen image when I built iOS and saved it.

But I saw only black screen instead of splash screen.

By the way I really thank for this amazing no-code platform service.

Not exactly sure the process with appgyver, however have you tried setting it in Xcode?

Oh… I didn’t know that I could set a launch screen using Xcode.
Is there a way to open an ipa file downloaded from the AppGyver website on Xcode?
