SetExternalUserId - System.ArgumentNullException: Value cannot be null. Parameter name: hashToken

[ChrisMonson]

Description: Attempting to set an external user id through OneSignal.Default.SetExternalUserId without supplying a hash token on iOS continues to throw an exception even after updating to v4.1.1. Looking at the change made in v4.1.1 it looks as though there is supposed to be a method overload for SetExternalUserId that does not have the optional hash token. This does not appear to be available in the actual v4.1.1 library. Rolling back to previous versions of the SDK has not fixed it as the issue seems to have been added in v4.0.0.

We are completely stuck on this issue right now and have had to give up on integrating OneSignal until this gets fixed.

Environment OneSignalSDK.Xamarin v4.1.1 installed via nuget Visual Studio for Mac 2022 v17.0.6 Xamarin.iOS v15.10.0.5

Steps to Reproduce Issue:

1. Install OneSignalSDK.Xamarin v4.1.1
2. Configure following OneSignal documentation
3. Attempt to call OneSignal.Default.SetExternalUserId("SomeExternalUserId")

Anything else:

Decompiled v4.1.1 OneSignalSDKInternal class showing no overload for SetExternalUserId without hashtoken OneSignal.Xamarin.Core.OneSignalSDKInternal.txt
