I have an Experience Builder App that has the following widgets:
Map Widget - pointing at a Web Map with a definition query for a subset of facilities
Floor Filter Widget - wired up to the map widget
Branch Version Management Widget - wired to a feature service configured with version management enabled.
What I am encountering is that while in the Experience Builder "Live View", the floor filter widget displays as expected:

When I preview the draft app in a browser, or view the published app, the floor filter widget is grayed out:

Dev Tools tells me I need to have a Facilities and Levels layer for the floor filter to work. I Definitely have those.

Is this an issue with Branch Versioned data not being compatible with the Floor Filter widget? If I remove the Branch Version widget, it works fine.
