Seeing the following message, when attempting today’s iOS 9 update?No official word from Apple on this but your one of millions of users attempting to update all at the same time. There however does appear to be a work around. Many users that were presented with this plugged their device into a computer and used iTunes to perform the download and update. Went thru flawlessly then.
Official iOS roll out days play havoc with apple server’s including the App update servers which appear to be a bit sluggish as well today.
Another tip for successful install.. Make sure you have room on your iOS device. If your NEARLY FULL, you could get error messages during the verification or the installation. As well as the device could perform very slowly so make some EXTRA SPACE delete some of the app’s your not using. The will still be available to you later in the iCloud.
Editor: First bit of a HICCUP APPS are not doing any updates on some devices. It appears to only be occurring on some devices as my own iPhone 6 appears to be updating and working correctly. However an original iPad Mini that is also being tested today has failed to update App’s repeatedly since the update.
