Just upgraded from 2017 to 2019, not a fan yet.

To busy to learn a few simple task. So I re saved everything back to 2017. Simple things like can not find the group - un-group buttons I had in the tool bar. Left click in the side color palette to un-check an  outline, button to cancel a contour. Don't really like the object page, Again, I just need time to go through all of it and setup to my liking, Just couldn't find must of these simple things in the option, customize page.
