Syncing app updates from iPad/iphone
I am currently having issues with syncing updated apps on my iPad and iPhone onto iTunes. I am using the most current iOS system on each device and the most current iTunes. I am using a USB cable connected to my MacBook Pro but not syncing of updates. I can apparently backup both devices to iCloud and the MacBook, the problem seems to be with iTunes alone.
Any suggestions or do I have to back up my apps on every device?
