Crashes Have Been Fixed 👍

Your mobile security app crashes every day, I have to delete it and re-install it every time to get it to open up, I have an iPhone 13 and I am running iOS 15.2, I pay 3.99 a month for an app that just doesn’t work, I have reported this problem twice to tech support and NOTHING, please fix this and give us an update ASAP. Thank you for fixing the problem, app works just fine now, support notified me by email telling it was a backend problem and it has been addressed, it has been a few days with no crashes, great job, worth five stars, again thank you.

It will block all of your incoming calls that aren’t in your contacts. I have missed so many important calls because of this. Customer service downs even know what you’re talking about when you mention it, just makes you reset your phone then reassures you that it worked. After 6 months I finally figured it out ON MY OWN because customer service is very much lacking in their knowledge of their products. There is also no information anywhere on the web. It will still block all calls even if you delete all security apps.

If you have downloaded it and it’s happening to you, go to MyAT&T and scroll past your devices then go to where the small print says active armor, the big print will say your security is our top priority. select manage subscription, scroll down, go to spam calls, select that, then select allow, and then go to fraud calls and select allow under that and now everything will come through including all of those types of calls and all your important calls. So no our security is NOT their top priority because now all the spam and all the fraud get to come through as well as important calls. The end.

Save yourself the games and hassle

It deserves 0 stars but it Won’t allow zero

I used this app for 6 months small issues until 2 weeks ago it started blocking everyone I mean everyone in my contact list, my husband, kids, parents, siblings, job, dr.’s office, attorney’s office, the calls don’t show up on my phone as missed calls, the calls don’t ring, I do not have my ringer off, I do not have DND on. 15 minutes later they appear in my voice mail and my loved ones text me asking why their calls keep going to voicemail.
It ask like a virus because I decided to delete it from my phone completely it started causing me to miss important calls. When I deleted it it was still blocking all my calls that I had manually unblocked before I deleted it. I had to download it again because I could not get any, zero calls, when I downloaded it again immediately unblocked in it’s list my contacts and not till then would my phone ring again. I am stuck with this virus I am afraid to upgrade to new phone because will this mess transfer when I spend $2000 on a new phone. I am stuck with it or my contacts cannot call me. It is working in reverse.😩😡🤬😭😤
