Ah ok.Have you tried restarting your iPhone? Press and hold both the power and home buttons until the Apple logo appears, then release both buttons and wait for the iPhone to restart.
BTW, I've moved your post to it's own thread where it will receive more attention.
Are you using an ad blocker?I was at the local Apple store this evening.
Employee directed me to the 9.3.1 update.
Stayed at the store until it updated.
Apps are starting to work.
However...
Safari is still not completing page loading.
I'm still frustrated.
Going back another day to ave my i5S diagnosed.
Looked at the i5SE.
Way faster than my i5S.
Contemplating purchasing the i5SE.
