Q: Group Messaging Issues

Hi, as of yesterday evening my group messaging isn't working. The group I message are receiving all of my texts but I can't see any of their texts. Individual texting is working fine. This problem began earlier in the evening and late last night I upgraded to the new iOS. I have already gone to settings > messages > send & receive, everything is appropriately checked. As well as my group messaging is turned on. I have rebooted my phone a couple of times. I have also deleted the thread and started a new one. But for whatever reason my group messaging is still not working. What else could be the reason?

HELP!

Thank you,

Nikki
