Weird symbols appeared when receiving texts from one person in a group chat. can anyone help?

Hey HoltzclawPO5,

Are you referring to the expressions symbols showing in the top right of the message? If so, you can find more info on that here: Use message effects with iMessage on your iPhone, iPad, and iPod touch

Respond to a message with expressions

With Tapback, you can quickly reply to messages with expressions, like a thumbs up or a heart. Here's how:

1. Open a conversation in Messages.
2. Double-tap the message bubble or photo that you want to respond to.
3. Select the Tapback that you want to send.

You can also use Tapback in group messages. To see who replied with a Tapback, tap it."

Thanks!
