We have WPF app converted using "Centennial" project. And we are using UWP Contacts API to add annotation for contact(https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/ContactCardIntegration). All works fine, but nothing happens when user tap on button "Call on an app" in "People" app.
Our app supports "ms-voip-call" protocol in app manifest:
<uap:Extension Category="windows.protocol">
<uap:Protocol Name="ms-voip-call">
<uap:DisplayName>appname</uap:DisplayName>
</uap:Protocol>
</uap:Extension>
Moreover protocol works fine when I use direct link for testing. UWP sample works fine.
I did not find this problem in known issues of "Centennial". So, I do not have idea what is wrong. Maybe somebody can give me advice.
