Xamarin LinkAssemblies build fails

I'm trying to build my Xamarin.Android app in Team Services and got the following error:

The "LinkAssemblies" task failed unexpectedly.
Java.Interop.Tools.Diagnostics.XamarinAndroidException: error XA2006: Could 
not resolve reference to 'System.Void.Android.Support.CustomTabs.CustomTabsIntent::LaunchUrl(Android.App.
Activity,Android.Net.Uri)' (defined in assembly 
'Microsoft.Azure.Mobile.Client, Version=4.0.1.0, Culture=neutral, 
PublicKeyToken=31bf3856ad364e35') with scope 
'Xamarin.Android.Support.CustomTabs, Version=1.0.0.0, Culture=neutral, 
PublicKeyToken=null'. When the scope is different from the defining 
assembly, it usually means that the type is forwarded. --->

I see that it is probably package related Microsoft.Azure.Mobile.Client

, but not sure what I would need to do to resolve it (I am fairly new to Xamarin, so not sure what to do with this information).

My minSdkVersion is 21.
