Have an iPad Air, newest update 9.3.1, there’s 2 apps that won’t update. Apple store show 2 updates required, when I open the Apple store for the apps the “update” button on each app is grayed out like it doesn’t need updated. I did a system reboot and new updates, still the same annoying issue. Usually when updates are needed you’ll see an “update all” on the top right hand corner, that’s not there either. If you want a photo let me know, picture is worth a thousand words.
Looking for a fix to this annoying problem.
