Group chat messages not sending on iOS 26.3

When I upgraded to iOS 26.3 on my iPhone 16, iMessage stopped sending group text messages to groups. I have MMS and RCS messaging activated and I've restarted my phone, etc. Any ideas on how to get this working again? It's definitely a result of the iOS 26 update, which I do NOT recommend.

I had the same issue that seemed to coincide with upgrading to iOS 26.3.


Go into settings, then apps, then messages.


scroll to RCS messaging and turn it off, then back on again. That fixed it for me.

I installed 26.3 the day it came out, no issue sending group imessage or MMS.

So not a result of 26.3.
