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'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?
