Since doing an update on i pad pro, a new section appeared on safari start page, with frequently visited sites. Tried to remove this, by pressing on each site, which temporarily deletes them but not permanently. I don't have a section in the safari app in settings, that shows frequently visited sites, that I can disable. Want to get rid of it, any suggestions please? Have tried deleting history, but if I go into the site again it reappears!!!!
