The app was great when I first got my phone. The notification kept going off really a lot. I checked the app and noticed the 1st 5 numbers had same number at time was exactly the same. This keeps happening. It was getting worse. I decided to count one day 75 with same number and time. I shut app off for 1 day. It helped for nearly 2 days. Started doing same thing. Even if I block numbers they still call block. Why should I upgrade when the free version is so bad. Please fix this app.
