Can anyone give me a definitive answer to this question?

I have a list Interface with 3 levels of heirarchy - Apiary, Hive, Inspection

This is for beekeeping. An apiary is a collection of Hives and Hives are inspected frequently.

On desktop in a browser (Safari) I can click into the Apiary Details and scroll down to the list of Hives and add a new one.

Still on desktop, when I expand the Apiary the interface shows its Hives as expected with an ‘+Add Record’ (why can’t I call them Hives?) button, and when I expand a Hive I can see the inspections as expected and at the bottom of the list of inspections is a ‘+ Add Inspection’. All good. Makes sense.

But none of those things are available in mobile (iOS 18.3.2, iPhone 12 Pro)

I can open an item at any level and edit that item but I can’t add new hives or inspections. Looks like this:

Am I missing something? This is a key feature for me and being able to do this in mobile is really why I’m building this app.

I read an announcement from a year ago that interfaces were supposed to work seamlessly on Mobile and I saw a thread about exactly this where the questioner says it works now. Is this a paid feature? It seems like such a fundamental capability. What good is a Mobile app if it’s read only? Data collection during the inspection is essential.
