Summary: I found a reproducible issue with Guided Access on my iPhone 15. After disabling Guided Access, it cannot be enabled again for approximately 30–60 minutes.
The problem exists on both iOS 26.5 and iOS 26.6.
Steps to Reproduce: Enable Guided Access. Use Guided Access for approximately 5–10 minutes. Disable Guided Access. Wait 1–2 minutes. Try enabling Guided Access again.
Expected Result: Guided Access should enable immediately every time.
Actual Result Instead of enabling, the phone displays:
"Guided Access Unavailable"
After this message appears, Guided Access cannot be enabled again.
I must wait approximately 30–60 minutes before the feature becomes available again.
Frequency
100%
I can reproduce this every time using the steps above.
Troubleshooting Already Tried Restarted iPhone. Force restarted iPhone. Turned Guided Access off and on. Updated from iOS 26.5 to iOS 26.6. The issue still occurs.
Questions: Can anyone reproduce this on iPhone 15 or other iPhone models running iOS 26.5 or iOS 26.6?
Has anyone found a workaround?
