Menu visibility issue for another user in mashup

I recently faced an issue in ThingWorx Mashup related to menu visibility for another user, and although I found a workaround, I’d like to understand why this happens and if there’s a better alternative.

Problem:

I created a mashup that includes menus and assigned visibility and runtime permissions to another user.

When I log in as myself, I can see the mashup and all menu details correctly

But when the other user (with runtime permissions) logs in, the mashup loads but the menu items are not visible.

What I Tried:

When I tried to fetch the same menus through a service call, the menus loaded properly — both for me and for the other user.

So, fetching via a service worked, but showing them directly in the mashup did not.

My Questions:

• Why does this behavior occur even after providing proper visibility and runtime permissions?

• Are there additional permissions or settings (like for entities, data shapes, or mashup parameters) that affect menu visibility?

• Is using a service to load menus dynamically the recommended approach, or is there a cleaner alternative?
