iPhone 6 Not Informing Me Of Available App Updates
I have an iPhone 6 running the current version of iOS (8.4). Normally, when an app update is available, my phone will let me know in "real time"..i.e. when an app update would become available, the red number badge would appear on the App Store icon to indicate this. Then, I'd open the App Store and install the updates (I do not have automatic installs enabled). Today, I, manually opened the App Store, went to the updates tab, and let the phone check for updates. A large number of available updates showed up. Some of them were more than two weeks old. Why was I not informed two weeks ago when these updates became available? Why did I have to manually open to App Store to become aware of these updates? I haven't changed any settings on my phone. How do I get the previous behavior back? Thanks.
