Portal Login for ArcGIS Vector Tile Style Editor

[KennethCompton]

Over the past couple week I have been trying out the ArcGIS Vector Tile Style Editor. I think it is needless to say that I love it. However, I want to be able to login to it with my Portal account. The site has a enterprise login option, but it automatically tacks on the ".maps.arcgis.com"  Does anyone know how to login with a Portal account to use this amazing tool.

Hi Kenneth Compton‌, I think we may need to get some further details about your ArcGIS Enterprise environment and workflow here to understand some more about the login you're seeing - I'll send you a message and follow up with you on this. Thank you!
