Can't update a certain application on iOS 9.3.2 It isn't only on iOS 9.3.2, it's been happening since the later iOS 8 versions.  But for some reason, I haven't been able to update a certain app on my iPod 6th generation for a while now.

The app indicates that it's preparing for an update when I tap on update.  After a few seconds though, it reverts back to the update button.

I've tried...


Restarting my device
Using "update all" instead of updating the app by itself.
Pressing on the update button several more times to see if it would begin updating.


But none of these have actually worked.

As said in the title, this only currently happens for one app.  All of the others work fine.

If anybody could help me with this, that'd be great.  This issue has been bothering me for a while now.
Remove the corrupted iOS app from your iOS device ( be sure to backup data prior step 1)
Shutdown your iPhone/iPad
Restart iOS
Reinstall the app from the AppStore
