Worklife Notifications not working post submission of skill connector/ Generate notification job

Summary: We are trying to see the and view the email notifications (and bell icon) for some of the features E.g.

1) Experts are notified when questions are posted.

2) Owner of the question is notified when someone responds.

3) Recipients are notified to take survey.

Once we made above changes we ran the Skill connector in Personal Brand Administration and also submitted the Generate Notifications for Work Life scheduled process However there is no notification in the bell icon or email.

Let us know if any one has faced the similar issue and if there is work around before we go ahead and raise the SR with Oracle.
