@jaosnz-rep I'm unable to reproduce your issue. Let me know if I'm doing one of the steps incorrectly here.

Confirming this is an issue, but not a regression.

Recently replaced CollectionView with a CarouselView to work around a different issue (layout resizing).
And now this issue which is present with CarouselView, but not CollectionView, has been made known to us.

Hi @PureWeen @rachelkang sorry for the late reply:
We verify that the issue is also repro on 8.0.0-preview.7.8814:

It is worth mentioning that creating a second project also seems to fail:

This seems to be an issue with “My Recipes” page not being updated, please let me know if we need to create a separate bug.

We verified this issue on 8.0.0-rc.1.9171 and made new findings.
The new recipe is not displayed after you create it, and will be displayed when you change the window size.
New recipes are not deleted when deleted and disappear when the window size is changed.

Verified this on Visual Studio Enterprise 17.9.0 Preview 1(8.0.3). Repro on Windows 11 and Android 14.0-API34 with below Project:
