What does a grey triangle with exclamation point inside mean?

[Android Central Question]

A triangle with exclamation point remains next to a person I have text and communicated with, what does it mean

Welcome to the forums. What phone do you have and what texting app are you using? What happens if you tap or long press that icon?

Usually means that text wasn't sent for some reason, tapping on it should result in a popup telling you text not sent, retry?....

It should mean that somewhere in your conversation there was an old text that wasn't sent. You can scroll thru the previous texts and look for the one with the triangle and if you send it again, both triangles should go away

I'm having the same issue with two text threads. I have the Galaxy Note 9, using Message +

Long press opens text menu, short opens message. Just like it would respond without the icon
