My iPhone 6 has had this issue for a while now and I have no idea why, when I tap the get app button, the circle rotates like it's loading something and keeps doing that for all eternity, I've tried everything from logging in and out of iTunes to fully resetting the phone to no avail, I used to download apps through App Store on iTunes (only way I found to do it with this bug) but they removed App Store with last update so I'm basically screwed. Can anyone help?
