Thanks for your interest in using Syncfusion products.
We have already logged an issue with “Application hangs when appointment collection is added dynamically in VisibleDatesChanged Event” in Xamarin.Forms (Android). The issue fix will be included in our upcoming Essential Studio Volume 2 release, 2016 which is expected to be rolled out by the mid of June month. We appreciate your patience until then.
