I am using the posts in order to make announcements to my clients. I am setting it up as 'Large' and showing the whole message, but for some reason these posts are coming in as regular chat messages. Only when you click on it they pop up with the regular size and view. Anyone had this issue?

Hey @keren b11! Post messages will appear as snippets if you have multiple messages. This cause them to stack up. Let me know if you have multiple messages.
