No logs unfortunately.
I was surprised too but according to the BBC website (UK national news) - " The alerts will work on all 4G and 5G phone networks and on devices with the following software:

iPhones running iOS 14.5 or later
phones and tablets running Android 11 or later

Older "non-smart" phones will be unable to receive the alerts, and nor will devices that are turned off or on aeroplane mode. "

@sb I'm just starting with QML too so don't take anything i say as a good idea! but in the documentation it seems contentComponents width and height should be set to the parent Page width and height NOT BottomEdge.

I was still getting the same problems after changing this so I tried setting the contentComponent to a Rectangle and nesting the PageStack inside. After this, myStackPage.height no longer resets to 0.

Hope this might help

I just noticed in fastboot the device name is 'bengal' and not 'billie'. Is this normal or do I have the wrong device maybe ?
