I have installed iOS10 on my iPad 4 - it all works well except for an odd behaviour with links. If, for example, I receive an email containing a link, tapping the link opens Safari but only to the home page. It doesn't load the website address. If I go back to the email and tap the link again Safari opens and opens the web address. I cleared the Safari History and Website Data. For a short while links opened as expected, but now, a few days later, the former behaviour has re-appeared. I have not observed this behaviour on my iPhone 6. Has anyone else observed this? Any clues about how to solve it?
