Yup, no idea if iOS 27.2 Beta 1 specifically fixed the issue I was having, or whether another update “in general” just managed to push things along, I have no idea. Technically, the Feedback is still open - FB23424437 - with a fresh sysdiagnose if it’s helpful.

Well, an unexpected install today. Nothing in the Dev updates, but by turning them off, I got a 580MB update, note the build number. Whether it makes any difference to me… dunno yet.

Update – iOS 27 Release Candidate The issue remains unresolved on the iOS 27 RC. After installing the RC, “Optimising Search and Siri” appeared and was allowed to complete. Apple Intelligence storage temporarily increased from 7.37 GB to 11.17 GB during the update, but subsequently returned to exactly 7.37 GB. Once optimisation had completed, Siri AI continued to display “Adding support for Siri is in progress” and remains unavailable. Invoking Siri continues to fall back to the old pre-Apple-Intelligence Siri interface. I have also re-enabled “Siri/Hey Siri”, completed the five-phrase voice recognition setup again, and restarted the iPhone, with no change. One additional observation: entering siri:// in Safari is recognised as belonging to an app called “Siri”, but iOS asks me to restore the Siri app. Selecting “Show in App Store” then produces “App Not Available — This app is currently not available in your country or region.” Device: iPhone 16 Pro Language: English (United Kingdom) Region: United Kingdom feedback ticket updated with fresh sysdiagnose file.

Well, it’s the RC version. Only been a couple of hours, so nothing 100% yet. But so far, no difference to DevBeta 8

Hmmmm Beta 8 seems no different. Same feedback form updated with a fresh sysdiagnose file.

Well, let’s give 8 a while. Remember I first joined in in version 2… I’ve been through 2, 3, 4, 5, 6 and 7 and STILL Siri Beta just sits there.

It’s Wednesday night, after a Monday night install. The optimising has finished. Siri is in exactly the same spot that it’s in every other time. I’ll add to the same feedback report, but it’s really starting to feel like no-one’s actually listening. We’re getting closer and closer to the RC version.

Well, let’s see if Dev Beta 7 gets me anywhere with Siri… it really is getting rather boring, that we’re 7 versions in and the new Siri just doesn’t install.

4 days later. Same situation. Pondering if Monday will be another update or not. Dunno if it’s best to stay on the stalled new version or to revert back to Apple Intelligence and the try and switch up again after next beta

Sadly, right now, roughly 15 hours into the newest Beta, the phone’s front-end is looking identical, but I do appreciate it’s not been 24hrs yet. Letting the optimising run it’s course. I’ve sent fresh diagnostic file to the same feedback ticket I opened several versions ago.

Downloading Beta 6. Lets give that a whirl.

3 days later. Phone still in the same state. Siri settings page has same message and the backup Siri is still the OLD old version. So I’m guessing the download/install of the NEW Siri isn’t going anywhere. Semi crossing fingers that the release schedule might now be weekly and possibly a further beta update today maybe.

I have waited over 48hrs since clicking on the text link to try out the new version of Siri. The “adding support for Siri…” message remains and I’m still on the OLD old Siri. I have updated feedback with a today with a fresh sysdiagnose.

Optimising has disappeared off of settings… so I clicked on the link to try out the new Beta Siri. I'm back to the message about “Adding support for Siri…” etc. I’ve updated the original feedback thread: FB23424437 (The new Siri is the old pre-Apple Intelligence version?)

Hiya. I have installed iOS 27 Dev 5 on the 16 Pro. It’s been 24hrs since the version 5 install. I am still intentionally on the old Apple Intelligence version of Siri because it says in settings that it’s “optimising search and Siri” and I’d prefer to wait until that’s done, before opting back into the new Siri AI beta. thus, right now, I don’t know whether the new Siri will or won’t install this time… Yet.
