One thing very important about Automations and Date Events

You cannot have multiple date events when using a Split Event (Split Tag)

Many of us will assume that after we split, and choose our dates as per the specific event... the automation will flow smoothly but that is wrong.

Tag 1: Event Date: 1st July (10 Subscribers)
Tag 2: Event Date: 2nd July (15 Subscribers)

The Moment is it 1st July, all the 15 subscribers from Event Date (2nd July) will get pulled into Tag 1 (1st July) as well.

This will only make sense, once you have this specific need or you are currently facing this challenge.

Hope this helps
