Bug: ConfirmExit doesn't work in windows desktop App

It turned out that App.ConfirmExit doesn't work in windows desktop App (Windows 10, last version of the Desktop PowerApp).
I just set it true and it true and it never shows the message on exit.

App.ConfirmExit still correctly works on Android app.

In browers also works incorrectly it always shows standard message and ignores message from App.ConfirmExitMessage property.


I appriciate any help on this.

Re: Bug: ConfirmExit doesn't work in windows desktop App

Hi @VasylV ,

Currently, the ConfirmExit functionality of App control is not supported in PowerApps Desktop Client App. The ConfirmExit functionality is only available in Browser and PowerApps Mobile App.


If you would like this feature to be added in PowerApps, please submit an idea to PowerApps Ideas Fourm:

Thank you for the reply.


I have posted this as idea suggestion:


But it seems to me that this is obviously bug, isn't it supposed that PowerApps should have the same functionality on different platforms? 
If no then another question is there some list of features supported for different planforms?
I should to use desktop as I need offline support but now it turned out that Windows is second class sitizen in Microsoft PowerApps :).

Also as I described above ConfirmExit works incorrectly in Browser as well - it never shows custom ConfirmExitMessage.
