I have done this before but $&@ iTunes has changed - again - gad I hate it!!

I want to go to an App that is backed up on iTunes - don't like the update. Below is the help file I found on line. Under item 5 - where the hell is the damn APPLY button now! iPhone 6. W7

So you were tired of those home screen badge numbers showing up on the App Store icon and you updated your iPhone apps on the go. Now whenever you use one of these updated apps it doesn't work properly or you don't like the so-called improvements made by the developer. How can you downgrade to the previous version?

1. Delete the app from your iPhone.
2. Connect your iPhone to the computer and open iTunes.
3. Do not update your apps in iTunes. Back up and sync your iPhone using iTunes.
4. When the sync is complete, click your iPhone in the left iTunes menu under DEVICES. Click the Apps tab at the top of the iTunes window. Find the app you wish to downgrade under Sync Apps.
5. Make sure the box is checked next to the app you wish to downgrade. Click the Apply button.
6. The old version of the application will be copied from your computer to the iPhone.

Thanks
