My Manychat workflow has disappeared & I need to update my information

I have left my previous brokerage and need to reset my email, login and profile. Also, the one workflow I had set up has disappeared. When I sign in, it is like I am starting from scratch. I went to the post that had the workflow and responded. I know it worked when I set it up as I had several test it. Now, I get nada. So, is there support for this? I paid for the year to have the workflow live.
