Hi there @bgiri,
Maddie here from the Customer.io Tech Support team :)
Thank you for writing in about your push notification daily reminder campaign. From what you have described, it sounds as though some users have entered the campaign but have not then re-entered.
In order for a user to re-enter a Campaign, they must have finished their previous journey and stopped matching the trigger condition/s then re-matched the trigger condition/s. Also, you need to have the Frequency setting on which, from your original post’s screenshot, I can see was correctly set up!
There is an exception for event and form-triggered campaigns as, by default, they allow users to enter the campaign each time the event occurs. With those campaigns, users can be in simultaneous journeys.
I have sent you a message in case you would like our team to have a look at the exact campaign you are referring to. Otherwise, I hope the above is helpful but feel free to post any other questions you may have!
