Colin,
I just looked at one of the apps my company manages that is on a Basic license. This app does have Access Restriction Profiles.
Hope that helps,
Mike
Standard & premium is Mendix' "standard" offering. Which they have for years and what their aim of business is.
To provide light weight use of the platform for smaller apps they introduced Basic. Which is just a single production server. Basic server configuration and monitoring and pricing per named user.
Suitable for simple internal apps for a limited set of users and server size.
If you have more wishes than the set basics, you need at least the Standard.
TLDR Basic is to start quickly an lure you into the platform😅
