If I edit the entry rules of a live series to add in more rules, will those already in the series be re-entered into the series?

Hey @amy b14​ Racheal from the Support Engineer team here 👋

No, users will not re-enter the Series, they will continue on down the Series. When making edits to a live Series, it is important to note the following behavior:

• If you add more content to a Series in a path a customer has already passed through, they will not receive this content.
• If you add more content to a point in the Series the customer have not yet reached, the customer will receive that content as normal once they reach it.
• If you add a new path to a Series, or a new entry rules block, customers already in the Series are eligible to enter these new paths.
• If you delete a block that customers are waiting at (e.g. a message or a rule block), they’ll be removed from that point. They will not proceed to any subsequent block in the flow.
• If you make content changes to a message that customers are waiting to receive, they will receive the latest version of the content when they come online.
• When updating Company Prioritization in a live series, that update takes effect for ALL Users, even if they've already entered the series.

When a customer leaves a series, they can still re-enter in certain scenarios:

• They disengaged from a path in the series, they can enter another entry point to the series, just not the same entry point they already disengaged from.
• They finished the series by completing all the paths, and you add a new entry point and path to the series later, they can enter that new path and receive those messages. They will not re-enter the paths they already finished.

If a customer exited the series by matching an exit criteria, they will not re-enter any other entry points in the series now or in the future.
