Apple introduced a feature in recent iOS versions called Advanced Tracking and Fingerprinting Protection. When enabled, this feature allows Safari (especially in Private Browsing mode) to bypass local and network-level DNS settings — including CleanBrowsing filters.
This means some websites may be accessible even when CleanBrowsing is configured correctly.
âś… How to Fix It
To ensure CleanBrowsing filtering works as expected:
- Open the Settings app on your iOS device
- Scroll down and tap Safari
- Scroll to the bottom and tap Advanced
- Tap Advanced Privacy
- Turn off Advanced Tracking and Fingerprinting Protection
ℹ️ What This Does
Disabling this option restores normal DNS behavior in Safari’s Private mode, allowing CleanBrowsing filters to apply correctly.
