Help with messaging between 2 users

So I’ve come across a problem with my messages. Before whenever I clicked on a user to display their conversation thread, it displayed the first users conversation thread. Now it displays each users conversation thread but when I type a new message and send it, it sends the message to the first user on my list. I’m not sure if this is an issue with my workflows or my type of content in each group, any help is appreciated!

What are you using to handle your messages? Is it a plug-in you found? Or home-grown?

It is home-grown. I used groups to navigate between “pages”

I actually just fixed my issue but thank you for replying!
