Certain website data sites can not be removed. Even after a reset they still remain. This only happened after updating to 10.3.
iPad Air 2 WiFi, Cellular, iOS 10.3
I found a solution and I originally posted it at Cookies won't delete on iOS. I found this thread has a lot of reviews and I will repost here.
I tested on both ios 11.1 beta 3 on my iphone 8 and 11.0.3 on my ipad.
I have this problem since ios 10 on iphone 5s. After I bought an iphone 8 recently and used the backup from the iphone 5s to restore, the "persistent" cookies migrated to the new device. I also bought an iPad Pro and used the backup from the phone to set it up, the "persistent" cookies migrated to the ipad as well.
All the operations and software are under windows. What you need to do is:
Step 1: Use iTunes or a third party software to make a backup of your device.
Step 2: Use a third party software (I used iMazing because it is the one I found that can edit the backup. This is not supposed to be an advertisement.) to edit the backup. To do this you first need to select the backup you made and click the edit button. Then you need to remove all the files in the editable backup under "File System/Apps/AppDomain-com.apple.mobilesafari/Library/WebKit/WebsiteData/WebSQL/ ". You will be able to see all the cookies that you can not delete at this location. I this the absolute path in the actual file system is /var/mobile/Application/com.apple.mobilesafari/Library/WebKit/WebsiteData/WebSQ L/.
Step 3: Usw iTunes or a third party software to restore the backup.
Note: The backup should not be encrypted.
The solution is quite technical, and I hope apple devs can fix this problem soon.
That still didn't get rid of the website data
Worked for me. Thank you.
After updating to 10.3.2 i can now delete all website data on my iPad Air, but my iPad Air 2 still has data that cannot be removed using 10.3.2.
This appears to have been fixed in 10.3.2 14F89
Already thought of that a while back and it didn't work when I first tried it.
The ever cookie problem hasn't been fixed in 10.3.2.
Thanks for the try but no good. Doesn work for me.
I updated to 10.3.2 (14F89) when it first came out and like I said before, it didn't fix the problem for me. It didn't fix the problem on my 5s or my 7 Plus. Hopefully it will be fwith 10.3.3.
Updated to 10.3.2
Still can't delete web data.
An updated phone isn't going to fix the issue. This isn't a hardware problem, it's a software problem.
It sounds like it should work but I've tried my best to follow the exact steps with no joy. I've even tried variations but none worked:(
I completely agree. It's sad, but not a surprise anymore.
Our IT dept calls it a "vulnerability" and wants is recommending phasing out iPhones for work.
Ever since iOS 10 this has been a problem. Sites can't be deleted. Some never go away and more get added slowly over time.
Thanks for your effort but even this did not work for me, and I'm getting more and more persistent cookies of this kind. It started with just two sites, now there are five ....
Why can't I delete website data in iOS 10.3?
