Link to public reproduction project repository
https://github.com/blackforest-tom/maui-mediaelement-bug-102
Environment
- .NET MAUI CommunityToolkit.MediaElement: 1.0.2
- OS: iOS 15.7.1
- .NET MAUI: 7.0.59
Anything else?
The issue is not reproducible if you use MediaElement v1.0.1, or if you swap out the AppShell and directly instantiate the MainPage by changing
MainPage = new AppShell();
to
MainPage = new MainPage();
in App.xaml.cs
Is there an existing issue for this?
