Customise this page does not make a user aware of changes to the page.

Issue
Notification mechanism - When the user clicks on the "Customise this page" link/button, a few sections in the page become editable, but screen reader users are not being made aware of it. There needs to be a mechanism put in place so non-sighted users are made aware of the customization options available.

Sufficient instructions - No elements, labels or cues are provided to help the users understand what are the customizations options available once "Customization" mode is on.
