Why can't I see my Guidance panel?

The Guidance panel gets displayed only if there's an active guidance process running on the specific records that you're viewing. You must associate the guidances you want to test or activate to existing records by running the Associate Guidances scheduled process.

Note: The Associate Guidances scheduled process is required only to associate existing records. New records are automatically associated with the appropriate active guidance.

You can set up the process to run periodically as described in Associate Records to Guidances.
