There seems to be a lack of clarity about how this Siri AI rollout is working. Does the indexing have anything to do with getting taken off the waitlist, or are they completely separate? Also, what is the expected wait time and has anyone gotten the new Siri after the initial wave of approvals (after 4 hours after the keynote)? The waitlist is extremely slow compared to the initial Apple Intelligence waitlist from a couple of years ago.
People that joined the waitlist on the day of the keynote should be getting their approvals by now, assuming they're letting people first come first serve. Once again, indexing does not seem to affect how fast you get in. Some of the "ask Siri" features seem to be buggy, both on Mac and iPhone, but it works pretty well for a dev rollout. I waited for around 48 hours and I joined the waitlist around 90 mins after the keynote ended.
