Just been on Apple chat. The annoying thing is they start the conversation like they know nothing about it!
"Oh wow, I understand how inconvenient and concerning it is to experience so many problems after updating to iOS 9.3. So you are experiencing an issue with accessing links within Safari after the update. I always expect updates to go smoothly, and this is definitely unexpected behavior. You have definitely made a great choice by contacting Apple Support today, you are in the right place for help!"
When you point out he hundreds of complaints on web
I want to let you know that our engineering team has received similar reports of this link behavior within iOS 9.3 and they are investigating the issue. As a temporary workaround, we can try turning off JavaScript, then restart your iPhone.
Said it hadn't worked for me.
Usual apologies etc then says use this link to report.
So everyone please use it. Not that it has ever worked for me with other issues. maybe I'll go back to windows and android.
