If we apply these changes, we should apply them to the TimePicker.

Hi, me and my team are migrating our Xamarin app to MAUI, and we need this feature to move forward, if anyone could take a look at this PR, thanks

Hi - as I understand it this fix hasn't made it into the release due to a merge issue. Would it be possible to get this looked at as this issue is causing a headache for us. Thanks

Dan

Hello Maui team. Is there any way this merge can be reviewed/approved? We are trying to convert our mobile project from Xamarin and this issue is preventing us from doing so. Should be a simple approval. Thank you!
