Tracking Email Opens with Einstein Activity Capture

Hi,

I'm looking to tracking Email Opens and our organization currently uses Einstein Activity Capture.

I have added both the Last Opened and First Opened fields to the Email Message Page Layout, but I am not seeing the email open status in the Email Message or in the Activity feed on Leads & Contacts.

I have also enabled the enhanced email tracking settings.

Does anyone know why I'm unable to see this information, even though all of the correct settings are turned on?

Thank you!
