Hello, awesome job first of all.
I downloaded the latest version (v.3.3.2) to use on my xamarin.forms project and got this error when tried to run on my android simulator:
Android.App.Notification/Builder .Builder.SetChannelId(string) xamarin forms
Nevertheless it runs fine on local windows. Have't tried on iOS.
I've downgraded to v3.0 and v3.2 and works fine on android.
