Sorting the customer column doesn't sort.
This is reproducible on Data Center: (yes)
- Navigate to Epics
- Click Column Shown > Customer
- Click the "Customer" column header to sort
The list should sort based on the customer.
Per Help Center article 10X: Manage Epics:
With the Epics page, you can manage your epics at a central location. You can select which columns to display using the Columns Shown option. To sort the epics, click the column heading.
Currently, there is no known workaround for this behavior. A workaround will be added here when available.
