You Cannot See all Feeds in My Updates as You See Using All Updates
Reproducing the Issue
- Go to Feed work center.
- Select My updates Option
Here you will not see all the updates generated by the system.
My updates option only show all the manual updates posted by user and it works as expected.
Just to clarify: Manual feeds are only those feeds which you write specifically on Feed work center or in any object using Post Update option, so basically you write some feed on your own. Any change to an object that generates a feed automatically in standard manner is called as system feed, then your change triggers a feed but you have not specifically written that feed.
