I have the LG Flex (T-mobile version) on Family Mobile. It's been working great, up until a few days ago, I stopped getting notifications (Facebook, Twitter, any app really) while using data. If I have sync on, I can get Email noticications. I get all the notificatoins just fine while using Wifi. The internet works just fine if I wanted to just browse, go on Facebook and all, just no notifications.
I've tried everything, even doing a factory reset, and still doesn't work. Is there something I'm missing? I haven't called Family Mobile yet, as it usually takes forever to get customer service there, and they aren't the most helpful people sometimes anyways lol. Thanks for any help!
