I am using Visual Studio 2015 with the latest version of Xamarin. I am connected to my Mac build server, and signed in on the welcome page. Every time I try to go on my storyboard, it says I need to upgrade to upgrade it to a supported format. When I do, I get an error telling me it couldn't successfully upgrade the storyboard. I will have the details below. How could I fix this error? Thanks in advance!
