STEPS TO REPRODUCE
- Login as Admin
- Create/update/comment/delete some pages
- Create an user (e.g. U1)
- Login as U1
- Go to User Index and click on Admin's profile
- Click 'Not following' button and select 'Start following'
- Refresh the page
- Observe the notification list
In the list there are no notifications, as the user (U1) has set the 'Start following' option after the events were performed by Admin. Will be displayed only the events performed starting the 'user following' moment.
Notifications for events performed by Admin are displayed even they were performed long before setting the 'Start following' option.
