I'm having trouble with the 1:N workflow from AG Utilities now that we've upgraded to Dynamics 365. I'm using 1.3.2.1. 
Here is the error I'm getting. Does anyone have word on whether there is an updated version of this ... or a better alternative? I've got *many* workflows using this plug-in, so changing it would be very time-consuming.
Sync workflow failed with error message - Unhandled Exception: Microsoft.Crm.Workflow.Services.InvalidCustomActivityExecutionException: Unexpected exception from plug-in (Execute): Gemina.CRM2015.WF.CrmDistributeWF.DistributeWFActivityOneToMany: System.AggregateException: One or more errors occurred.
