Group messages not working

Hey there,

If you’re in a group message and stop receiving messages, check to see if you left the conversation. Open Messages and tap the group message. If you see a message that says you left the conversation, then either you left the conversation or you were removed from the group message. You can rejoin a group message only if someone in the group adds you.

To start a new group message:

1. Open Messages and tap the Compose button .
2. Enter the phone numbers or email addresses of your contacts.
3. Type your message, then tap the Send button .

If you have other issues with a group message, you might need to delete the conversation and start a new one. To delete a group message:

1. Open Messages and find the conversation that you want to delete.
2. Swipe left over the conversation.
3. Tap Delete.

In iOS 16, iPadOS 16.1, and later, you can recover a message if you deleted it within the last 30 to 40 days.
