I’m attempting to arrange deep linking/common linking for my .NET MAUI app. All the pieces seems on the floor to be arrange in line with the MS documentation, nevertheless when accessing hyperlinks it merely makes use of the browser. This occurs in each Android and Google.
The specified behaviour is in order that any visitors to https://app.rackemapp.com (which can sometimes be by a QR code) will set off the app to open.
In Android I examined it with a customized scheme of rackemapp:// which labored, so I do know the bottom logic works, I simply can’t get the gadgets to know that app.rackemapp.com visitors ought to open the app.
The curl testing to succeed in my AASA file works okay (no redirects or 40x errors) and the diagnostics device on the system detects it as a legitimate common hyperlink.
How do I make it open my app?
