NAV 2018 Extension - New pages in menu suite visible in CU8 but not in RTM

Hi,

I have developed an extension towards a 2018 CU8 docker installation. Here, everything works fine. Now I need to publish the extension to another version, 2018 RTM. The installation is fine and everything is OK. But nothing can be seen in the menu suite! Everything is visible in CU8 though.

I can see that the new tables, pages, code units, etc exists, and I can navigate to them by using lookups from other fields, also I have an installer script creating some web services and job queues, and they are all there. But no new pages etc are visible in the menu.

Any clues how to solve this? I really need to sort this out asap.

License is OK. I've restarted services, synced tenant, and similar.

" UsageCategory = Administration;
ApplicationArea = All;
PageType = List;"

Is the code used to make the page searchable.
