Just updated to ios 18.1 and it appears to have broken my group imessaging?
In the text box for the group chat i only see ‘text message - sms’.
Previously it was showing ‘imessage’
imessage to individuals work fine.
When people message in the group chat it comes through as individual messages.

Have tried restarting and turning imessage on/off but no luck.

Anyone else experience this? Is this an issue on my end or with the other group members? Any ideas on how to fix this?
Thanks
