Hey everyone, Ever since I received my 7 Plus 2 weeks ago, i've been experiencing a lot of issues with group texting (MMS not iMessage). I always seem to have an issue randomly with my old devices (iPhone 6+, iPhone 6S+, Nexus 6P) where I would stop receiving group texts and it would be almost like a hang. Randomly later or after a reboot i'd get a flood of old messages. In my case now I don't receive any texts at all and this happened at least 4 times. I tried the following: Rebooting, deleting the thread, toggling airplane mode, toggling LTE>4G and toggling Group Messaging and MMS. I even restored my phone from an iPhone backup in iTunes with no luck. The only thing that worked to get NEW messages is toggling Group Messaging and MMS off, reboot, turning them back on and rebooting. All the old messages never show up. This happened prior to upgrading to 10.1 also. I called AT&T, I did their troubleshooting steps and they found another issue with group messaging with iOS 10. If you start a group convo with iMessage and then later a recipient turns iMessage off, there is no way it sends as a regular text even after their regular sms text comes through. "Send as text" is not an option. Therefore, they will not receive any of the group texts. AT&T forwarded me to Apple where I gave a lot of my troubleshooting and information to a Senior Advisor. They are getting back to me on Monday after they speak with Apple engineers about the issue. I'm just glad there wasn't anything important or emergency related in those group texts.
