I'm trying to use declarative methods to updated related records when one record changes.
The two types of objects are related through a junction object, which means I cannot use a process builder to update the related records.
When I try to use the flow to achieve this, and when I set the flow trigger as "New or updated records—flow makes fast field updates", the "Update records" element is not available.
How can I update junction and related objects when a record is updated using declarative methods?
