New Ticketing System Issues

Is there a way to rollback to the previous version of our ticketing system?  I see what you're doing, but I think it needs more testing.  I like the appearance, but joining a ticket/closing a ticket is cumbersome or broken.  Also, I missed a chat earlier because it kept trying to make me do a tutorial.  I closed out of it several times and it kept coming up.  Also, I know it sounds small, but I got a chat from someone who joined and left right after joining.  I now have to select whether or not if it's solved, pending or unsolved.  She joined accidentally.  I guess I can choose solved, but that isn't the case.  It's been frustrating for all of us in our department.  Thank you for your consideration.
