ArcGIS Pro 3.1.2; mobile geodatabase
I have a FC joined to a standalone table. I want to sort one of the joined fields.
In the attribute table, if I right-click a joined field, the sort ascending and descending options are greyed out.

Could ArcGIS Pro be enhanced so that we can sort joined fields?
It looks like this is an ArcMap equivalency issue — it's possible to sort joined fields in a Oracle 18c 10.7.1 EGDB (mobile GDBs aren't supported in ArcMap).
