Running the wasm version I got this error:

I tried to run the command on Powershell but didn't work.

On Android, there's a different behavior than Windows.

When I click/tap on the card it doesn't move to be above all the rest, like happens on Windows.

The background color doesn't respect the theme, as you can see in the screenshot:

First issue: did you run the power shell as an admin? It should be run in elevated mode.

Second issue: there seems to be an issue with Canvas SetIndex methods on Android >= 32.

It works on iOS, Mac OS, WASM and Windows.

Yeah, I did that as an admin and didn't work for wasm. Probably something on my env.

I could run it on Android, but I've to set the manifest manually

Thanks for your PR @Onotseike , sorry for taking so long to do the final review
