I used to be able to use that "Clear History and Website Data" option under the Safari settings to log out of websites or clear website data. On iOS 11 beta (I am on beta version 2), it seems like it is no longer clearing some or all parts of the history/data. For example, on iOS 10 if I went to facebook.com, signed in, went to Settings to clear history/data for Safari, then went back to facebook.com, I would be signed out. On iOS 11 beta, if you do the same steps, you are still signed into Facebook. Is this a known issue?
Safari "Clear History and Website Data" doesn't work
I too am seeing this. Anyone have any thoughts as to why?
I'm having issues with some sites and the cookies that remain. Only solution is to enter Private Mode.
