How do I turn on Catalogue mode in the new Hika?

I have been turning catalogue mode on and off with no issues for the last several months , but have updated to the new version and the menues have changed, but the help menu is still telling me to go to 'main' then turn on catalogue mode.
My only options in main are:
-Put store offline (which I have had to do temporarily to stop more orders while we stocktake)
-Editor
-Default

Where do I now find catalogue mode? When I manually turned off the add to cart buttons in products it didnt remove them from the site either.

Site is: www.territorydayfireworks.com.au but I doupt that will help you much as hika is offline.
