Screen readers do not announce changes that automatically occur upon entering Email in the edit field, leaving users unaware of dynamically updated information.

### Expected Behaviour
Screen Readers should announce automatic changes in edit fields to keep users informed of dynamically updated information, like loading or progress info and once the page has loaded. It should announce the page title as well.
### Actual Behaviour
Users do not receive auditory feedback from screen readers when automatic changes occur on entering Email ID in the edit field. Screen reader remains silent once the new page opens.
