It could save a lot of time if the Native Builder would check the validity of the provisioning profile and distribution certificate when configuring a build for distribution.
In my case, I forgot to check my provisioning profile and it turned out that it was expired. It resulted in a failed build in Visual Studio App Center. This can be avoided if the Native Builder checks and warns about this at the moment the user adds a provisioning profile or a distribution certificate. And at the moment the user clicks the Build button with an invalid profile or certificate, the build does not need to be attempted because it will fail.
