How can I show a message to the user (preferably a pop-up) after he/she signs out?
You can add a call nanoflow button to the page where you want to be able to signout
The nanoflow does 2 actions
- calls a microflow that opens a page with (only) the appstore widget url-redirector on it (https://appstore.home.mendix.com/link/app/113/)
- Have the url-redirector refer to either an anonymous page in your app or an external page if need be
That should do the trick. If anonymous doesnt have acces to the nanoflow the button will disappear when you navigate back to the page.
