Hey @Jenny_Cadwallader1 welcome to the Asana Community 
The feature should still show, I am not aware of any issues currently.
Have you checked various tasks in different projects and it does not show in any?
If so I recommend looking through the troubleshooting steps such as checking whether there any browser updates or checking your extensions which might be causing an issue.
Also logout and in again and in case it is still not working then I recommend reaching out to support
When doing so please ensure to provide them all details about the problem and ideally a screenshot as well.
