Following a record only produces automatic updates when feed tracking is on for that object. Here is how an admin enables it so followers actually see field changes in What I Follow.
- Open Feed Tracking in Setup
From Setup, enter Feed Tracking in the Quick Find box and select Feed Tracking. The page lists every object that supports it on the left.
- Select the object and enable tracking
Click the object you want, for example Account or Case, then check Enable Feed Tracking. This switches on the record feed and lets you pick fields.
- Choose the fields to track
Select up to 20 fields whose changes should post to the feed. Pick the few that matter, such as Stage and Amount on Opportunity, to avoid flooding followers.
- Save and verify
Click Save, then edit a tracked field on a sample record. Confirm the change appears in the record feed and in the What I Follow feed of a user who follows it.
The master switch per object. Off by default for most custom objects; some standard objects ship with tracking already on.
The specific fields whose changes generate feed posts. Auto-number, formula, roll-up summary, and encrypted fields cannot be selected.
A per-user setting under My Feeds that auto-subscribes the creator. Does not cover tasks, events, dashboards, or child records.
- Tracking more than a handful of fields per object floods followers and drives them to unfollow within days.
- Owner change does not auto-follow the new owner; cover that gap with a record-triggered flow that inserts an EntitySubscription.
- Followers never see tracked changes on fields hidden by field-level security, so two users following the same record can see different feeds.
