Ques: Given this review: "Frustrating I have had this app for years and it's been great but lately it is not working at all. It immediately stops backing up when the screen turns off. So I have to keep backing things up 5 messages at a time out of thousands. Or let my screen on for hours which is not ideal. I've never had this problem before but lately it is making me want to download another backup app that actually works" Would you recommend this app to a friend?
