In Adobe Sign, no manage features available

I have Sign via Adobe PDF Pack and was using the sign feature for several months. Recently the track and manage functions (the function to view who has signed, who has not signed, send reminders, see activity chronology, etc.) are simply not visible. There is a blank white space in the screen beside the document that has been circulated for signature.

Where all the signature management features used to appear, there is just a blank space.

Adobe support is apparently non-existent for this, hence the appeal to the forum.
