Unable to Install apps onto my iPad (Stuck on "waiting...")

For the past several days, I have been unable to install ANY apps onto my iPad. When I click "GET" and then "INSTALL", it just says "Waiting..." below the app icon.

This is what it looks like (not from my iPad, from Google):

I've tried the following to attempt to resolve the issue:

(I had no other apps updating/installing)

• Restarted the device


• Turned on and off the device


• Updated the iOS 8 software to latest version


• Went to Settings>General>Reset>Reset All Settings


• Restarted AppStore


• Synced my device with iTunes


• Deleted app and tried to reinstall


• Logged out of Appstore


• Logged back in to Appstore


• Turned off/on wifi

In addition to not being able to download apps, I can't download books from iBooks either. I don't know if this is a software issue, or if it's a network issue.
