Can't Remove a Few Cookies Safari 10.1
After Safari update to 10.1 with Yosemite, several cookies can no longer be removed. Did the usual Prefs>Privacy>Manage Website Data>Remove All. When done, 3-4 cookies come back.
Tried Develop>Empty Cache, Always block cookies, turned WiFi off, cleared history, cleared iPhone & iPad history but these cookies still come back.
FWIW, two of the cookies are Yahoo & eBay. After deleting the cookies, I'm no longer logged into yahoo or eBay. So something got erased but the list in Manage Website Data still shows them being there.
Bug, something new, suggestions for really removing cookies?
Thanks
