The adaptivegrid control is visible in uwp apps, but not in android and wasm.

Describe the bug

Hello

Added Page to Shared project and AdaptiveGridView. When executed in UWP, the output is normally displayed on the page. However, when I target and launch the Android app and WASM, the controls are not visible. Is it normal that it does not appear to be a prerelease?

• [ ] Is this bug a regression in the toolkit? If so, what toolkit version did you last see it work:
