ArcGIS Pro 3.5.0. After creating polygons in an existing feature class, they are visible after saving them. When I go in the attribute table and calculate geometry, the polygons disappear from the map.
run check geometry or repair geometry on the featureclass when you are not editing
maybe the rings are reversed

Possibly just a graphical bug; do they appear if you re-add the data to the map or refresh?
What type of symbology are you using? Single symbology or other?
