    Hello @BrendanZagaeski ,

    @BerayBentesen, thanks for the report. Whenever you have a moment, if you wouldn't mind copying and pasting that forum comment into the "Description" field on a new bug that would be perfect.

    You can file the bug against Visual Studio or Xamarin Studio, depending on which one you are using:

    Of course, if you'd like to provide any additional details such as "Windows version information", "Mac version information", "Android SDK Tools, Platform-tools, Build-tools" (see the KB article), that would be excellent too. If you notice that the problem does not happen with a new from template project, then if you can attach a test case on the bug report that demonstrates the problem, that will likely save some back-and-forth too. Thanks again!
