Hello everyone, I have a 2019 iMac and the catalina version. I don't have a phone because I broke it so I use my iMac instead. My friends added me to a group to work on our class project but I was not able to see the invite. I have two of my friends number registered but I don't have my other friend number registered. I am not able to see the group chat or join it but I can text just like normal. I don't know if I need to make the group myself because they tried creating it and I got a email instead of text, and I don't know why is this happening. One person tried to text me without making a group just a conversation but it goes to mail. Please help me I need to fix this.
