I have created a sample where try to reproduce the issue:
Issue13092.zip

But cannot reproduce it:

Tested with Xamarin.Forms 5.0-pre5 on iOS 14 and Android 10. Could you review the attached sample or attach a sample where reproduce the issue?

Some questions:

• Do you use Visual?
• Are you using DynamicResource, AppThemeBinding etc?

Thanks for the reply!
I've find that the reason of my problem is I forget setting the Offset of the GradientStop, after setting the Offset, everything goes fine.
(BUT, on Android, it's all fine without setting the Offset of the GradientStop)

Ohh, I see. Thanks for your feedback!. I sent a PR to have the same behavior between platforms.
