I updated to iOS 9 and the only issue I can see this far is with Safari cookie settings. I cleared all cookies and website data. Set the cookie setting to 'Always block'. Loaded a dozen or so sites. Opened the cookies and data list in Settings to find many third-party cookies and data listed. It should still be empty after setting to 'Always block, shouldn't it? I set the setting to 'Allow for sites I visit' and logged into a few sites. I manually closed Safari, set the setting back to 'Always block' and reopened Safari to the sites I had previously logged into and found that I was still logged in to all of them. Since all cookies are blocked, shouldn't that prevent sites from checking for a login cookie? I also found that deleting all of the third-party cookies and data seems to have logged me out of everything despite not touching those specific login cookies and data. I tried a few other things and none of the cookie settings seem to have any effect in Safari in iOS 9 on my iPhone 6. Can someone tell me what I'm doing wrong? Or is this a case of a Safari data handling bug?
