See who has premium
Nothing is worse than being left on read. So sometimes I’d like to be able to know if the other person has premium so I know if they see when I open their message or not. Sometimes I’m just busy and can’t respond right away, but if I know they’ve seen that I’ve read their message, I’d try to answer more quickly. If they can’t see it, I wouldn’t feel anxious for reading it and not responding ASAP.
