ArcGIS Pro 2.9.5; File Geodatabase:
I have two standalone tables. I join them using Add Join, resulting in a 1:M join.
In the attribute table, I can't sort on the join table fields; the sort options are greyed out. Whereas the input fields are sortable.
Could the attribute table be enhanced so that sorting is supported on join fields when the join is 1:M?

For what it's worth, in 3.3.0, I don't have this problem if I specify that the join will be one-to-first in the Add Join tool. I only have this problem with one-to-many joins.
