Custom URL Scheme Not Launching App

Hi guys,

Trying to add a custom URL scheme to my app so i can interact with the web side of the project when users create content and share it with other app users via email etc.

So, I'm trying to launch both in Safari on the device and on Simulator, but both times I get this error popping up in Safari.

I'm using this URL: myappname://

Cannot Open Page
 
Safari cannot open the page because the address is invalid

I've added the following into my tiapp.xml, and it also appears correctly when the project builds in build/iphone/Info.plist

<key>CFBundleURLName</key>
                <string>com.app.myappname</string>
                    <key>CFBundleURLSchemes</key>
                    <array>
                        <string>myappname</string>  
                    </array>

I can launch other apps, like Citymapper for example, in Safari using citymapper:// as a URL scheme.

Any ideas what I could be doing wrong?

Running on iOS 8.2, using Ti 3.5.1 GA

Any ideas?
