Issues since updating IOS.
I have had a couple of issues since updating IOS. Imessage won't work. It asks me to sign in with my apple id, which I do (and I know this is working). It then asks me to confirm the email address and then verifies this. I then come back to the screen asking me to sign in with my apple id. Repeat the above, and so i I go round in circles. In settings, message asks me to sign in with my apple id and then I go through the above. I do not appear to be able to switch message off or on.
Second issue is that it will not find my logitech keyboard cover. Thirdly, not that important, but irritating, is that with some apps (Hay Day, FB,) I get a messge 'Connect to iTunes to use Push Notifications'. I press OK and it goes away.
iMessage, keyboard and apps were all working fine prior to updating.
Any ideas?
Thank you
