Why can't I delete website data in iOS 10.3?

Tried this "solution" twice and now I feel stupid for being so gullible. Like most of the stuff on the internet, this too is nonsense. If you return to advanced browser settings, the zero byte cookies have returned. Simplest solution of all is to: email the offending company and let them know why they won't get any more of your business, post details about the company's disrespect for customers on their web discussion board or fakebook page, encourage others to boycott the offending company also. You have to remember that corporate execs are stupid. Actions that diminish their profits hit them right in the greed, the only thing they are capable of understanding. Fight back, don't back down, eliminate your assailant by any means required.

By the way, this undeletable cookie problem has haunted Safari since 2010 if you check the Apple support forums. As usual, apple chooses to fix a problem by ignoring it. (Remember the itunes blank store page problem?) Also, cookies that are difficult to delete have been a problem at least as far back as 2008. Unethical companies are always looking for new ways to insult and assault customers.

I always clear out website data/cookies after a lot of internet use and noticed since the iOS 10.3.1 update, the phone stores website data. Even though after deleting, the phone will show 0 bytes, but the sites are still listed under the advanced tab. At one point I had over a 100 sites listed, and the phone seemed a bit slower. I found the only way to clear this is a master reset and set up as a "new iPhone" which is a pain. Not sure if this will work, but so far, so good-no website data storage......yet.

I have the same issue on iPhone and iPhone.

I "Clear History and Website Data" and also under Advanced > Website Data > "Remove All Website Data" but if you go back to the "Website Data" screen pages are still listed. I tried deleting them manually by swiping left on them to reveal a "Delete" button for each item but that doesn't work. It removed a few but not all. The items remaining have "0 bytes" of data but they won't delete from the list at all.

This has been an issue for a while now and although it's not stopping me from doing anything it's frustrating!

Yes this worked for me. You do have to follow the steps in ORDER. Also, I set my Cookie and Website Data to "Allow from Websites I visit" and you need to clear your browser data prior to starting. It took me a couple of tries with Safari in Private and non-Private mode to clear it out. (iPhone 6 - iOS 10.3.1)

Both my husband and I have same issue on our iPads , we both have iPad Air 2

and cannot erase all history,,,

have you come up with a fix yet ? ,makes a person nervous to use iPad for personal reasons (banking etc.) as we do not feel secure with these sites staying attached

I had just updated at 1pm est to 10.3.2

IT took a bit of time but after it rebooted and I signed in all was gone. I have only tested 20 r so sites that locked me before and I was able to delete data.

The new iOS update 10.3.2 (14F89) has not fixed the problem for me. The website data is still there I have tried everything including, remove all website data, edit then removing individually by clicking the red/white icon, swiping to remove and also restarting iPad. REALLY ANNOYING THEY ARE STILL THERE...all 9 of them!

Update

Seemed to be working yesterday but after logging in to a financial website I couldn't delete the website data. I tried another one that was locked in before and sure enough it stayed. I am now going to report to Apple. At least it seems other sites that were staying won't stay now.

YYes I thought all was good yesterday but today the other sites stayed. I was in contact with my case # and support ongoing and it is still being worked on for a future update. It's in the engineering hands.So I will keep checking as I hope others will also call to express concern. Private browsing doesn't seem to hold anything but not good on shopping sites.

It is a pain to wipe the iPad and iPhone out and restore just to clean so I installed Firefox. The new version allows me to delete all website data and work pretty good. I am only using it for everything I look up and check searches for at this time. I hate having search history stored!

Great news! If you are still having this problem it will be fixed in iOS 10.3.3. I just installed and currently running the developer's beta 1 and the problem is completely gone. Fingers crossed it stays that way😁

I hope so. I thought it was good when I installed 10.3.2 all the website data was gone and it seemed good buuut the next day I went to some sites like Citibank and poof, locked in. Macy's another one. To name just a couple. Thank you for sharing. Please keep us updated.

Definitely not fixed with 10.3.2, full update via iTunes and the previous cookies are still there.

I've switched to Firefox too but there is nothing to say this is successfully deleting the cookies, you just have to trust they are gone.

A lot of the persistent cookies in Safari show as 0 bytes but even the ones with data in don't seem to have any value with regards to remembering contents of shopping baskets etc, so not sure if they are actually doing anything?

There is definitely a serious issue with website data. Although I only have 4 persistent cookies, every so often a great number of previously deleted cookies jump back into the list. When deleted again they are removed from the list but obviously lingering around somewhere.

It's extremely frustrating that Apple have left this issue unresolved for so long...

I Agree. I have all toggles switched on for deleting in firefox so all appears to be good so far. the good thing is we have a 10.3.3 beta tester in this thread and I hope they stay in and keep us updated. Privacy is important but I have held off on a vpn until the issue is resolved. I don't have firefox synced from the iPad to the other devices at this time just in case.

I'm hoping that it will be fixed with the next version, but I'm still skeptical that it will be. Hopefully it is fixed like you said, but I hate that we'll have to wait like 2 months to find out for sure.
