Same occured in my Android app caused by the AppThemeBinding :

Is there a work around for this issue? I am facing the same issue with version 4.0.10. But I'm not really sure this issue gets really triggered by this nuget, maybe xamarin or something else.

[sofiaprice]

I am having this issue on both iOS and Android on 4.0.10. It is triggered when I navigate to another tab with lotties from a tab with lotties, then back again.

[MMieszko]

I have the same. Lottie animation is an EmptyView template for CarouselView.
