The following behavior is not working in CMS 4.2.0
“Menu Boards are edited independently to Layouts, so there is no need to access or edit the Layout(s) the Menu Board has been added to. Changes will be available in the system straight away ready to be picked up by Players on their next collection, with no need to make any edits to Layouts!”
Existing layouts and/or players will not recognize the changes to products (add, delete, change).
Only a layout → draft → publish will trigger the change.
