App Store won't install apps I'm trying to re-download, I see the iCloud icon instead of INSTALL icon Once I've deleted an app from my iPad, I only see the iCloud icon with a down arrow rather than the "Install" button.  When I click on the iCloud icon, nothing happens. I've looked at App Store sometimes can&#39;t install, iCloud icon instead of INSTALL icon, but I know my iCloud and App Store passwords and they've been updated in my settings, but I never get asked for any password.  On rare occasion, when I click on the iCloud icon I see the timer circle that indicates something is downloading but it goes away in a second and the iCloud icon returns.  

I have no problem downloading new apps, but ones I've deleted I can't re-download. How can I fix that?
Strictly speaking, the cloud/arrow button is the install button. You are missing buttons to acquire the app and add it to your account (either GET or PURCHASE). 

Try signing out of your iTunes Store account, restarting your phone (power off and on), and sign back into your iTunes Store account. That cloud button should still appear and allow you to add the app to your phone (it should turn into a loading spinner, and then an OPEN button).
