Since the most recent Experience Builder update, I’m seeing the error “Relationship not found in the map” when using the Feature Info widget. Related records no longer appear in the popup.

The related table is present in the web map, the relationship is correctly configured, and the related records display as expected in other apps like Map Viewer and ArcGIS Pro. This issue only seems to affect popups in Experience Builder.
I didn’t make any changes on my end and noticed this start over the weekend. Just checking if anyone else is experiencing the same issue or has found a fix or workaround.
