Workaround

MrtnSys commented 1 year ago

Can confirm this issue on Android 12. When you open a child page on a tab, then switch to a second tab and then switch back to the first tab, the custom titleview of the child page is gone and it displays the default titleview. This is urgent, because it breaks my customers app now. Does anyone already have a workaround with a custom android shell renderer?

MrtnSys commented 1 year ago

Downgraded from Xamarin Forms 5.0.0.2545 to 5.0.0.2291 again. That fixed the issue on Android again. On iOS i am still using the custom renderer from #15512 "Shell TitleView Not Working in iOS 16 [Bug]" to fix the titleview bug there. What a mess with titleviews at the moment.

Even though I upgraded the project to the latest version (Xamarin.Forms 5.0.0.2622), the problem persists. Shell.TitleView Content disappears on tab change. This is urgent !!!
