Abandoned Cart Pop Up Not Collecting Contact Details Of Some Guests

Hello Villatheme,
I have purchased and been using your Abandoned Cart Plugin since July this year or so. The abandoned Cart Plugin is set to collect the Email Addresses and Phone Number of anyone before he/she can add a product to Cart but unfortunately, it has not been working for some Guests. This is not making me get maximum value from the Plugin and my marketing efforts.

The Attached image would explain better.

Hope to hear from you soonest.

Regards.
