Many to Many Relationships

Hi Team,

I am having an issue trying to get an attributed many to many relationship to appear in portal, specifically in Experience builder.

Right now I have a Point layer of Ports, and a Table of Ships.

In Arcpro I have an attributed relationship class (Many to Many) set up that works just fine in Pro. But I am unable to find the relationship in the Forms widget in the Web Map, or in the Edit widget in Experience Builder.

My question is there a specific way to set up M:N relationships that I am missing?

Regards

Map Viewer only supports 1:M and 1;1 relationships. M:M is not supported.
