Hi friends, The objective of the contact update notifications is that the project/team is reminding the assigned user (record owner/responsible user) to keep progressing with the contacts assigned for them to steward.
Therefore, the update trigger timing is based off the contact status. The update needed is reset by comments from the assigned/responsible user or status change. It can be overridden with a trigger a the top of the contact record. Other users (digital responders and dispatchers) frequently add details to the conversation without actually being a substantial progress update and therefore do not automatically reset the update needed trigger.
All of these settings can be tweaked or completely turned off in the Admin > Settings (D.T) > General Settings tab > Update Needed Triggers section. There is a tick box to enable/disable the update needed notifications and the timing and text of the individual notifications are set within that section.
