When loading fails on mobile, there is no way to know why

[MartinZikmund]

On mobile there is no way to access Developer Tools, there should be a helpful message telling the user what can be done (e.g. refresh), as well as what has gone wrong

This is before the app is loaded?

Can it be handled by regular application exception handling or it's not loaded yet?

Could we have something that displays the error message instead of the icon when in debug?

This is before the app is loaded, .NET is generally not loaded. Some of it needs to be handled by the code in the runtime, some of it on our end when we show the error icon. The error is a tooltip that does not show on mobile at this time.
