Can’t even use the app – One Tap Access Widget for Notification Center Review

I’m so frustrated. First I downloaded the free version. I opened it and wend to add 1st favorite. I got a message that I had to go to Setting>Privacy>Contacts and click on OneTapAccess to allow it access to my address book. I tried to do that but when I clicked on Contacts, OneTapAccess was not listed for me to choose. I then went to the support on the app and wrote an email. But next I got a message saying that the address was no good. So I went to the app store to write a review and I go a message saying I couldn’t write a review unless I owned the app. Do I have to purchase the app to be considered owned by me and then be able to write a review? I next went to their website and wrote another email for help. I didn’t get a message saying the address wasn’t good and am now waiting for an answer. I then deleted the app and reinstalled it to see if that would help. It only helped to allow me to right this review. I will change this review if it ever works and the problem is solved. I’m writing this here so if it happens to anyone else maybe they can read the reply back to me from the company as to how to fix the problem.
