Are Apple Intelligence features still inoperable?

Update #3: Apple AI services still unavailable in updated MacOS 15.3.1. VPN removed, issues persisted. Error reporting still unavailable. ChatGPT Plus account integration also not working. No response from Apple Engineering yet. Will update again if any more OS updates and/or Apple Engineering guidance.

Update #2: Apple Support still unable to resolve the issue for me. I have reinstalled the MacOS without avail. Apple says it will continue investigating as it has no explanation yet for the (1) AI services not working or (2) the error reporting tools in the apps not working.

Still hoping...

Thanks for helping me dig deeper.

I'm not using Private Browsing. I do have a Palo Alto Networks VPN. The failure of Apple AI and error reporting persist with it on or off. I can't really remove it since I need it for work: campus resources like library databases, servers at the university, and so on are not accessible without a VPN.

If VPN software is the issue, that's a significant fail. The student and instructional labor market in higher ed in the US alone is probably close to 1 million users (my university alone is likely ~ 45,000 users at the 50% Apple adoption rate). Add corporate (or cautious) people who use VPNs, and that seems like a massive oversight for a company with tremendous resources (and hardware margins) like Apple.

I hope to get another update from Apple Engineering next week. I'll report back if they discover anything!

Update: Apple Support was unable to resolve the issue for me and discovered in the process that feedback on Apple AI (Use Report a Concern to share feedback about Apple Intelligence - Apple Support ) isn't working across my apps either (e.g. mail, Notes, Pages, etc.). Apple Engineering is now investigating. If I learn of a fix, I'll share the remedy here for others who may have experienced the same problem I am encountering.

I hadn't seen much reporting on the broad failure of the Apple Intelligence features, so I was hesitant to post. My settings are below, and you can see examples of the errors I receive in Apple Mail and Apple Notes. The laptop is shutdown and restarted every day. Other than this feature being a complete fail, it works as expected in office, remote, and home locations. Nothing else seems affected.

Any ideas on a next step welcome!

NOTES (using text from public LinkedIn post)

Good point: it may be helpful to have both sides working in parallel. The IT folks in my school haven't encountered any issues like mine with other faculty and staff who bought Macs recently, but I can certainly flag it for the campus level tech in case it's a rare issue (e.g. affects only me in my school but occurs more frequently elsewhere in the other 25 schools and colleges on our campus). More to come after any updates from either Apple Engineering or my campus. :)
