I have had a couple of strange issues develop on my iPhone 6+ running the latest DP.
If I try to update any apps it shows the circle with a blue solid square in the middle but the download never progresses, it just hangs at the initial point.
I have tried to delete and re-download but same story.
I have tried downloading a new app I dont have from the 'featured' content on the App store - same story.
Also if I try to check whether there is a software update on the Settings -> General -> Software Update, it says "checking for updates" for ages and then I get a message, "Unable to check for Update, An error occurred while checking for a software update"
All was normal up to a couple of days ago. Wondering if anyone has seen similar problems? (I have seen a couple of reports of similar issues with the App Store.)
