The tooltip does not work even without any of the capture code. The problem is that the TextBlock you have in the Grid is on 'top' of the button. You can try using a stack panel or rows/columns in grid to make sure mouse events go to the button.

 <Grid x:Name="grid" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
     <Button ToolTipService.ToolTip="Tooltip">Hello</Button>
     <TextBlock>Test</TextBlock>
 </Grid>

A little more explanation. Many controls attempt to fill a grid cell (if they are contained withing a grid). TextBlock is one of those controls. We can debate whether it should or not, but currently it does. So when you place the TextBlock after the Button in the markup, it will overlay the whole grid cell, covering the button. That you can see the button through the background of the TextBlock is beside the point. Some other things to notice is you aren't getting the pointer effects (e.g. pressed and released states) and the click event doesn't fire. This is because the text block is getting these events. Also, if you add a tooltip to the text block, it will show up even when you are hovering over the button.

Couple of ways to fix this.

1. Change the layout so that the TextBlock does not take the full grid cell (e.g. Horizontal and/or vertical alignment is something other than stretch, a MaxLine property or an explicit size).
2. Swap position of the Button and TextBlock so the Button sits on top of the TextBlock.

Thanks, I was trying to reproduce a bug in a MAUI Windows app where tooltips stop appearing after a while. The TextBlock wasn't really relevant to my case, just accidentally staged while trying to come up with a minimal repro to determine if the behaviour I was seeing was a MAUI bug or a WinUI bug. So my bad, this doesn't work as a repro. I'll have another go and re-open if I can show it's a WinUI 3 issue.
I note that some input issues I was experiencing in MAUI were fixed by updating WinUI 3 to 1.4.240211001 anyway, so might not be a problem any longer anyway.
Thanks again for your help!
