Keep getting message on screen that vpn blocking Call Protect from working & asking me to disable vpn which I've done but the Same bs message comes through. Also saying in play store that Call Protect not optimimized for my device that I Bought thru ATT!! It just recently quit working & I've had this device since last October! Att needs to do better than this for its customers. So there's no Call Protect available anymore for paying customers. SO glad I passed on that 3.99 a month scam!
