Q: Just got the IPhone 6  and updated to IOS 9.2. I am having a hard  time sending group messages, sending and receiving multi media messages from groups and individuals and receive group messages hours to days after they were sent.

I just got an iPhone 6s and installed IOS 9.2 as soon as I got it. I am having a hard time sending GROUP messages, and often receive messages sent in a group text hours to days later. Recently I started having trouble sending and recieving multimedia messages to individuals as well as groups. This seems to happen with iMessage as well. My group messaging, IMessages, MMS and SMS are all on. I have tried many different troubleshooting suggestions such as 1) turning phone off then back on 2) turning off then on imessage, MMS ,SMS and group messaging 3) turning off wifi assist 4) Reset network settings 5) disconnected wifi all together. The only thing I haven't tried is a factory reset. Any other suggestions before I try that or is anyone else having this problem!? Thanks in advance!
