Unable to create or edit label classes for web map with group layers in ArcGIS Pro.

Solução Provisória

• Open the published web map and define the label class in Map Viewer, then open it in ArcGIS Pro to enable or modify labels or label classes.
• Open only the hosted feature layer for the group layer from Portal (published with the same web map) to enable or modify labels or label classes.
