Was restoring from iCloud to my new iPhone 6s. I left it going overnight and it still had a few apps hanging the next morning. But they just won't download. Nor will any updates to current apps. I tried deleting and reinstalling the apps from scratch and I get the message that the app cannot be downloaded at this time. I wasn't able to download ios 9.0.1 ota either but managed to sort that via iTunes. New apps I've never had before seem to download perfectly fine. Any idea what the heck is going on?
