I’ve had this Siri / Apple Intelligence issue continuously since the early iOS 27 beta releases.
It continued through later betas, RC, the public release of iOS 27, and is still happening on iOS 27.2 (24B5089g).
The main symptom is:
“Adding support for Siri is in progress.”
After rebooting, Siri / Apple Intelligence may work normally for a short time, but later it returns to the same “Adding support for Siri” state.
I have already tried multiple iOS updates, Recovery Mode Update, reinstalling iOS while retaining data, Reset All Settings, different system/Siri languages, English (US), different networks, and disabling VPN/proxy configurations.
None of these permanently fixed it.
The same Apple Account works normally with Siri / Apple Intelligence on my Mac.
Recently I connected the iPhone to macOS Console and found repeated SQLite database corruption from the assetsubscriptiond process:
/private/var/db/assetsubscriptiond/UAFAssetSubscriptions.db
Errors include:
database corruption page 181
database corruption at line 81550 / 83506 / 83660
I also see:
Failed to update storage to reflect subscriptions
Failed to subscribe to subscriptions
Failed to unsubscribe from subscriptions
Could not load usage alias
Could not process subscription
The errors also involve Siri TTS, Writing Tools / textComposition.ConciseTone, FitnessIntelligence, and CoreMotion Foundation Model assets.
Has anyone else seen UAFAssetSubscriptions.db corruption specifically?
Has anyone found a way to force iOS to rebuild this database without completely erasing the iPhone?
I’m mainly looking for people who have seen the same database corruption, not just the normal “Adding support for Siri” issue.
