Hi I am using the VS for Mac 2019 version (latest as of this post) with the Syncfusion plugin however it produces a non-buildable solution. The issue seems to be w/ the UI Kit for Xamarin and not the plugin. I am using all of the latest Nuget packages for both Xamarin Forms and Syncfusion UI Kit. I have attached a screenshot for your review.

There error seems to mention that it's having trouble finding INotifyPropertyChanged:

../CheckoutPageViewModel.cs(22,22): Error CS1061: 'CheckoutPageViewModel' does not contain a definition for 'NotifyPropertyChanged' and no accessible extension method 'NotifyPropertyChanged' accepting a first argument of type 'CheckoutPageViewModel' could be found (are you missing a using directive or an assembly reference?) (CS1061)
