Facebook app won't install
I periodically delete and reinstall apps on my iPhone to free up storage, usually Facebook and Twitter. Last night, Facebook would not reinstall, saying the update is temporarily unavailable. Currently, Facebook is listed on the storage page, but the icon is blank and it won't delete and on the app store, I tap open and it doesn't respond. Is there something that can be done to get Facebook back?
iPhone 6, iOS 10.0.2
