Having just installed X19 update I'm unable to access the design gallery. Usual menu paths followed (Utilities-bars-galleries selected) and Design Content download but only page a layer gallery appears on the right hand toolbar.
Selecting 'File/New from content catalogue' gives message 'designs gallery must be enabled' which it is.
Had same problem with last update but downloading 'design content' from help menu solved problem - but not this time.
Anyone had same problem or can offer a solution please
