Feed Tracking Limitations

• Reports on feed activities don’t include information about system-generated posts.
• When feed tracking is enabled for person accounts, users can follow and see updates to account fields, but not to contact fields.
• Feed tracking for events doesn't include requested meetings. Requested meetings are tracked only after they’re confirmed and become events.
• User can follow activities and knowledge articles in a Chatter feed. However, the Follow button in the Action column for activity and knowledge article list views isn’t available.
• When feed tracking is enabled for Knowledge, the feed always refers to knowledge articles by the name they’re given when created. If a knowledge article is renamed, this change isn’t reflected in the feed.
• If you disable feed tracking for topics, users can’t follow new topics. They can continue to follow the topics they followed when feed tracking was enabled. The followed topics count toward the maximum number of things they can follow. Use the Connect REST API to stop following topics after feed tracking is disabled.
• Most feed tracking changes are reported in the What I Follow feed. However, users’ own changes to tracked fields are reported in their profile feeds instead.
• When an object owner is transferred using the mass transfer record feature, the feed doesn't capture the action. The object owner change action is captured on the feed when a transfer is done manually.
• When feed tracking is enable for the Activity object, the Task field can't be selected for tracking. Task is an internal Salesforce field that indicates the type of activity represented by the record and can't be updated once set.

Feed Tracking Limitations on External Objects

• Field history tracking isn’t available for external objects.
• Record feeds aren’t available for Salesforce Connect external objects that map to high-data-volume external data sources.
