I'm having a HUGE problem here, I updated to IOS7, and updated all my apps on WiFi. I got a call today from my cell phone company saying I used 5 gigs of data so far, and im only 3 days into my cycle. I look up to see what going on, lo-and-behold, viber has used 4.7 GB of data in 3 days! How is this even possible? I have no video messages or picture messages, and have been using the app for months without problem. Is there anyone else seeing this issue or a possible fix?
