I've been on Arhd 62 with Sense 6.0 on my M7 AT&T for a month now. Everything is great except Blinkfeed stopped refreshing this week and won't show any content. I tried everything with auto sync, rebooting, etc. Also I will not get any MMS, pics or group. They show up in preview notifications bar but when I go to messages they're not there, like they don't exist. I tried different APN settings and this forum isn't easy to navigate. I found numerous APN settings that vary. Can someone point me to the right ones for AT&T with LTE and MMS? Or how else to solve these issues? Thank you.
