When having for example device set to US culture , the TimePicker shows 12h time format, which is correct.
If you want to keep the US culture but want to use the 24h time format, the TimePicker does not apply the format, it still uses 12h time format.
The same behavior happens in the time part of the DateTimePicker

Workaround:
If I wrap that command call in an ICommand then no issues.
If the user is clicking on a slider value that toggles the visibility of the green box to change (either show or hide), the slider thumb continues to follow the mouse cursor even after the drag should have ended. This continues until the user explicitly clicks somewhere on the slider again.
If the AutoComplete is nested inside a modal Popup and Unfocus() is called on SuggestionItemSelected or Completed, the cursor/focus stays within the AutoComplete.
The same does not happen (the AutoComplete is properly unfocused) when the control is placed in MainPage.
The ItemsSource of the views is populated in the ViewModel of the page. This is done in a command that is triggered by the NavigatedTo event of the page, which is forwarded via EventToCommandBehavior from the Maui Toolkit.
When using the RadCollectionView the loaded items are no longer displayed.
When the ObservableCollection of the items is completely reconstructed and reassigned the display works.
Null reference exception occurs with maui 10.0.90
Just add the datagrid definition in xaml or code behind and exception occurs.

When navigating to DataGrid examples, xaml binding errors occur for ActualWidth and Header Text.
Still, the app runs as expected.
