Poor performance opening page containing SvNavigationDrawer

[James Lavery]

We've got a Xamarin.Forms app which is using FreshMVVM for its MVVM framework, and we've added SfNavigationDrawer to the pages.

We've noticed that there is a significant delay when navigating to a page with SfNavigationDrawer on it. The system hangs for 1-3 seconds before any part of the target page is displayed.

Is this a known bug?

You say " The issue will be fixed in 2017 Volume 3 Main release which is expected to be rolled out by the end of July 2017."

1. Is the issue fixed in "2017 Volume 3 Main release"?  And was it released by the end of July?
   
2. How do I know if I have "2017 Volume 3 Main release"? (I use Nuget version 15.3.0.33)
3. Is there a release history log somewhere where I can see the various releases and what they contain?

I use the latest release I can find, and I still suffer from extremely poor performance on sfNavigationPage loading.
