What a mess . 9.3. Safari freezes. Some websites completely unusable. Links in mail work, but returning to mail shows error message ‘no mail selected’. Earlier the uodate failed as it reported that there was no internet connection availabke, although there was. My ipad air 2 was mutilated by this update. I did not want to update after the first fail, but unfortunately my ipad updated overnight. I updated my iphone 5s too. Hope that is not affected, but I fear it will be mutilated by Apple as well.
