Option to read in audiogram deleted since iPad OS 18.1

There was an option to read in an audiogram which you could use to improve your airpods pro, so no need for the airpods pro 2.

The audiogram could be generated with help of an app like mimi hearing test.

With the introduction of iOS 18.1 the option seems to be removed, probably to encourage people to buy airpods pro 2.

I understand the business model of Apple, but it ****** me off.

Why is this Apple?
