Hello, I am trying to configure Meeting Rooms in the Indoors Viewer app (ArcGIS Enterprise 10.9.1). My Indoors database was created with the latest version of Pro and has the Reservations feature class included and also the Units FC has the reservation_method field associated with the DOM_RESERVATION_METHOD domain. The reservations layer is published as an editable feature layer. I have calculated the reservation_method field so that bookable units have a value of 1 (showing description "Reservable") and vice versa for non-bookable units. My data is in an enterprise geodatabase and published as a feature service (for use in Space Planner) which is what is included in the web map.
The Indoors Viewer app automatically detects the Reservations layer and the tick boxes for hotels and meeting rooms are both on by default. From the docs, "If all the prerequisites are met in the web map, the Meeting rooms check box is automatically checked." It seems like it's picking up the field on the Units but in the Viewer app I'm only getting a quick access button for hotels but not for meeting rooms:

Anyone seen this before or have any suggestions? Thanks in advance!
