Standalone table not appearing in new map viewer, only map viewer classic

Question

I shared a feature class and a file geodatabase table to my Enterprise Portal as a web layer.  I need to have both the feature class and the table in a web map.  When I make a map with the new Map Viewer, the table is nowhere to be found.  But when I use Map Viewer Classic, the table is in the map, just like I need.  But I need to use the new Map Viewer because Map Viewer Classic is of course obsolete.

I did confirm that both the feature class and the standalone table are listed in the map service's REST endpoint.

There's no editing involved - no versioning, no feature service, etc.

I am the owner of the web layer / service.  And I am working on the web maps as myself, the same account that is the owner.

I'm using ArcGIS Pro 3.0.3

Enterprise 10.9.1 build 28388

My organization cannot upgrade to Enterprise 11 yet.  In fact, the work I am trying to do with this web layer is part of our work to get all our map services running from Pro, as part of our preparation for upgrading.  So I have to get this work done before we can upgrade.

I did see something on Esri Community from 2 years ago about related tables not showing up in the new map viewer, like Esri hadn't built this functionality yet.  I don't know if this is related.

A crazy thing is that on another Enterprise Portal we have (the Dev one), an essentially identical web layer with a table DOES show up in the new map viewer.  That Portal has the exact same version and build as the one I'm having the problem with (which is our Production portal), and the services have the same settings.  I don't see how the new map viewer could be acting differently in the two Portals, but it is.

Does anyone know how to get the table to show up in Map Viewer?  Is it a bug?

I'm able to see the pop up just for the feature layer and it is not connected to the related table. How were you able to relate them together? They pop up separately. Not when I click the feature and it shows related records? What am i missing?

Working on it. Using a Feature Service instead of a Map Service brings the related tables and it's possible to add the related records in the Popup. However, it's not practical at all, you can see the related records one by one only and there is no "Show related records" option to automatically open the related table filtered with the related records of the selected feature.

They mentioned in that ESRI blog from 2022 that was one of the "What's next?" features but it has apparently not been implemented yet.

I saw that was possible to return a related table in HTML directly in the popup but it's way to much work for what we need so we will stick to the classic Map Viewer.

I've the exact same issue, I can't believe it. Using ArcGIS Pro 3.3 and ArcGIS Enterprise 11.3. The data is from SQL EGDB and it works perfectly with Map Viewer Classic but not the new Map Viewer.

The only way to add the tables in my map is to use the Add Layer from URL option but it's still not recognized as a related table, part of the underlying relationship.

I can't use Map Viewer Classis. I'll have to reconfigure my mapping service, republish it and then try to somehow summarize the data in the popup of the related feature. It's not ideal and won't be as good as the usual related records option.

What a pain. Thanks ESRI to keep publishing new tools and pushing everyone to upgrade while it's not 100% functional yet.
