I apologize that this topic has fallen through the cracks. There is no news on this front; at this time, the team still has no plans to implement a delete functionality for timeline events.
While there has been quite a bit of engagement on this thread, I don't think the feedback has been as visible to the team members as it could have been on the HubSpot Community Ideas Forum. That's on us for not moving the discussion over to the Ideas Forum sooner.
I couldn't find a similar feature request on the forum, so I created this one. If you wish to have the ability to delete specific timeline events in the future, please upvote and comment on the post.
I recommend including as much detail as possible per these best practices . The more the product team understands a feature's use cases, the more accurate they will be if they scope the feature.
Thank you for your understanding. I will close this topic to maximize feedback on this idea.
