Since I installed this app, I have had trouble with my incoming calls. Even people on my contact list including my daughters and sister are blocked. Despite my working with their support, they have been unable to fix the problem. From about 7pm on 2/1/2022 till I uninstalled the app about noon on 2/2/2022, no calls . The blocked calls don't appear on your call log, so you don't know that someone tried to call you. They also charged me for Jan and Feb2022 even though I have 1 yr sub till 9/22.
