iOS 10.3 Safari cookies won't delete

Is this bug fixed in iOS 11?

Thanks for the report!

Fixed on iPhone for me but not on my iPad. I had the beta on the iPad whereas I did a routine update to IOS 11 on the iPhone. Not sure if that makes a difference.

Did you restore your iPad from a backup that included the cookies?

No. Exactly the same bug remains.

You’re in the wrong discussion thread for an OS X problem.

I’m hoping for a fix in High Sierra.

Well stated and yes, Apple, please resolve. In the meantime, I'll keep using Firefox.

Please validate away, before your high horse gets tired.

Nope, problem still here as of 11.2.6 on the 6s.

still using safari 10.1.2 and the persistent cookies remain, does anybody have any solution/response from apple yet on how to remove?

Does 11.3 resolve this issue?

I have the same issue and have tried all the suggested resolutions short of full resets in part because if you have done a backup you will only reinstall the problem. I am in the UK and the problem sites are:

• iPhone 6s = weather.com
• iPad Mini 4 = argos.com & eBay.co.uk
• MacBook Air = eBay.co.uk

Additionally further rogue websites show numbering anything from 2-30 depending on when you look and this after not having launched Safari!!!!

I've had the same issue with being unable to delete a number of "0 Bytes" cookies on my iPad for a while, but recently an eBay.co.uk cookie of 508KB size began to exhibit the same behaviour - at which point I "snapped", enough is enough! I found a solution, however it's a little long-winded and requires a Mac:

1. Connect the iOS device to a Mac and create a backup using iTunes
2. Open the backup using an explorer/editor tool such as iBackupBot (I was a little dubious about using this at first, but it was signed by a registered developer and did not require installation nor did it ask for a password input at any stage, so pretty safe)
3. Navigate to the folder "User App Files > com.apple.mobilesafari > Library > Webkit > Website Data"
4. Delete all files and folders in the enclosed IndexedDB folder - this is where the 508KB of eBay data seemed to be
5. Delete all files and folders in the enclosed WebSQL folder - where all the other "0 Bytes" cookies are stored. I was amazed there were even cookies in here which didn't show up in the Website Data view in Settings. Mine had a whole trove of cookies from argos.co.uk, ebay.co.uk, and uk.farnell.com amongst others.
6. Restore the backup to your iOS device using iTunes

This was sucessful for me on both my iPad Pro and iPhone SE - both on iOS 10.3.3. I can't confirm if it will work for iOS 11 devices, but from what I've read many people have found the cookie problem to be fixed in 11.1.2.

After chatting with Apple Support about this issue, was able to clear the problem with the "Reset All Settings" selection under Reset in the "General Settings" menu. If you do this make sure you backup first as you will need to do restore

to maintain your settings.

I performed the reset 24 hours ago and so far the issue has not returned
