No fireworks on apple 12 phone

Hello!

Thank you for reaching out!

If your device doesn't automatically send a message with fireworks, you can manually add the effect by holding the send button and selecting "Screen" at the top. You can swipe to the desired effect.

You can also choose different effects, too!

Hope this helps.

Best.

It's up to the sender, not the recipient to add the effects to their message. You can't add them to an incoming message. You can add them to a message you want to send to someone.
