I've had several app updates behave oddly over the past few days. On the update page the status dial sticks and doesn't move. When I tap on it to pause the update and then go look at the actual app, the app icon has the blue dot as if the update was successful, but the App Store retains the badge showing that there's an available update. Other apps are updating normally, but a select few are freezing like this. Is this a known issue? I can delete and reinstall, but this isn't a very good fix for a lot of apps.
