Abandoned Cart is not working?

Hey! I installed Abandoned cart plugin, as my store is custom one so email notification service is taken by SMTP service. But issue is whenever anyone puts products to cart then it is displaying in order section as abandoned but it is not showing in Abandoned cart. Not a single product and not a single email is sent.

What is the problem???
I searched for answers as well as i contacted to the team. But i didn't get answer. As Facebook pixel report saying 17 add to cart and 6 initial checkout. but not a single result i am getting in abandoned cart report. I have no problem if it takes some time to display but if it takes more than a day or week then it will be problem.
