iPhone 16 Pro failing to install new Siri Beta

I am currently on Apple's Dev Beta V4 for iOS 27. The first version I installed was the Dev Beta V2, I am desperate to try out the new Siri AI Beta, but it's just not installing for me.

I have the ability to "turn siri off" then "on again" and find I get the 2024 Apple Intelligence version fine.

But if I choose to try out the new AI Beta, I'm left with "Adding support for Siri is in progress. Siri will be unavailable until the update is complete." It's been in that state for over 48 hours in Beta 4 and I'm left with the OLD OLD Siri globe from pre-Apple intelligence.

Am I being too keen and just not leaving it long enough? Or is there a genuine issue at Apple's end, in regard to getting the new Siri to actually fully install?

Thanks for your post.

Being stuck on "Adding support for Siri is in progress" with the old Siri globe usually indicates that the background download for the on-device AI assets has stalled?

Can you provide screenshots and errors you are receiving? Please keep them save as I think we going to move fast to file a bug for iOS 27 beta 4 in this case.

If your iPhone is running low on space. What’s the free space you have in the device? Do you have a sysdiagnose to check the error in case is storage?

Ensure your iPhone is connected to a strong Wi-Fi network, turn off Low Power Mode if it's on, and plug the device into a charger. Leave it locked and charging for an hour or so?

screenshots of what specific would help?

phone has been left plugged in asleep overnight attached to a very decent WiFi broadband. I must admit, low power mode is turned on… but not actually “active“ if that makes sense.

@nitram1872 Thanks for the details, I do not see anything that will cause the issue. Maybe we need to go deep in the sysdiagnose to get the reason of the issue. May I ask you to file a bug and attach the sysdiagnose?

Once you open the bug report, please post the FB number here for my reference.
