Hi SimonaA,
This depends on whether the time to pause the customer journey and modify the content is before or after the official start time.
The customer journey here I set up is to send emails.
If the email is changed before the official start of Customer Journey, the email sent to segment is the one that was replaced.
At first, I set the email of Set background. Before the official start at 2:00 pm, I changed the email of Test Email. The result shows that the email received by segment is Test Email.


If the email is changed after the official start, the email sent to segment is the first one before.


Email set at the beginning

After the pause, change the email and restart.


Regards,
Qingqing Xin
