I have the same issue. Do you have any fix or workaround for it ?

Any news around this? I have the same problem. And I discover that with iOS, tabs don't enter in a loop but the ContentView inside one of the TabViewItems disappears. Not sure if this is related or not.

To be fair the tab view is quite buggy, hope some of these are resolved in maui.
