Why doesn’t Apple record its events in Apple Immersive Video?

It would be really nice, but I have never seen any document explaining the reason for this.

Have you already sent feedback with a feature request?

Apple Vision Pro

no, we can't

these forums are user helping other users like yourself, it's sort of going to a physical apple store and asking other customers their advice

This is a user helping users with tech questions forum, we are not apple and apple do not read your posts here

but it would seem a bit amateurish, if such a big company as apple would not look at them.

Apple guarantees that every feedback request will be read. We do not necessarily get a reply. But it is useful to use the form to submit feedback for feature requests.

Only, you cannot be sure, that your request will be seen here by the developer team.

When you use the feedback form you can be sure that someone will see it. It is stated in the feedback form:

"Use the form below to send us your comments. We read all feedback carefully, but we are unable to respond to each submission individually. If you provide your email address, you agree that we may contact you to better understand the comments you submitted."

You are also welcome to post feature requests in the Apple communities, as long as they are constructive and helpful, like your request. This is stated in the Apple Support Community Terms of Use,

see paragraph B.3: "Post constructive comments and questions. Unless otherwise noted, your Submission should either be a technical support question or a technical support answer. Constructive feedback about product features is also welcome."

For problems like bug reports that need additional documents and data to be able to describe the problem in more detail, I am preferring the feedback-assistant. It is available, when we are using a beta version of the software or are having a developer account.
