For various reasons (e.g. Apple servers are down or you have connection problems etc), apps you are downloading from the App store may not be successfully installing or have installed incorrectly.
How to fix:
- Tap the app that is not downloading / installing so that it says “Paused” and then tap that app icon again to see if it resumes downloading.
- If the tip above does not work, launch App store and search and find the app you are having problem with (app that stuck on “waiting…”). The app download button will say “install”. Tap install (reenter your Apple ID and password if you are prompted) to see if it resumes downloading.
- If the tips above do not work, reboot the iPad, iPhone, or iPod touch by pressing and holding the Sleep/Wake button for a few seconds until you see the “slide to power off”; follow the instructions and slide the button to power off the device. When your device is turned on, it will likely ask you for your Apple ID and password to resume the download.
