Install App Updates
Issues with app performance could emerge at any time and that's why we recommend keeping a close eye on the App Store in the days ahead.
Some developers were quick with iOS 9 support updates, others are taking their time. These support updates should help your apps retain their stability and that's precisely why you probably want to install them. ou might want to check reviews first before you do though.
If you don't have automatic app updates turned on, now would be a great time to do that. Head into Settings, App and iTunes Store, and flip on the Updates toggle. This way, you don't have to be bothered with manually updating.
