Hosted feature layer fields with apostrophe characters (') in the domain codes and descriptions are sorted incorrectly in ArcGIS Pro 2.8.2.

Workaround

Uncheck 'Show domain and subtype description' to sort the domains.

The issue does not occur when the same layers are exported to file geodatabases.

Another workaround is to remove the domain from the affected field in ArcGIS Online. Click the Data tab in the item details page, then Fields view, then click the name of the field to remove the list for. On that page, click the pencil icon to edit the current list. Within that view, there is a button to Delete List in the lower left.

In ArcGIS Pro, the Remove Domain From Field tool also removes the domain and serves as a workaround.
