Cannot Update Apps in App Sstore
I'm signed into both my device and the App Store successfully using my AppleID, however any time I try to manually run updates on apps the store asks me to sign in again (even though I'm already signed in). I put in my password and each time it asks and it always fails. I can still, however, download and install new apps. Signing out/back in to the app store and device, and rebooting the device has not helped.
