Supply Status - Interface Screen for Weekly Mailer subscription does not function

Problem Statement

Interface screen allowing the Supply Status users to set up suscribe or unsuscribe to the weekly summary email does not seem to function.

After trying both below cases:

• removing a subscription for my profile (ESPAGJ)
• setting up a subscription for another profile (CUML)

it all ends up with the spinning wheel that never closes. Changes are then not taken into account.
