Dynamo 2.01 in Revit 2019.0.0.405 - not working

So my version of Dynamo 2.01 works with Revit 2017, but does not do anything with my 2019 version.

Is there an additional item that needs to be modified to make it work? Dynamo says its up to date.

You can maybe install the latest daily build of dynamo 2.1.0 and see if it solves your issue.

Will try that. Thanks.

I thought however Dynamo would have picked up on that.
