I'm having the exact same problem on my iPhone 5s, iPad mini (both are jailbroken) and on a non-jailbroken iPad4. The Update All is not clickable (like there are no actual updates) and when I click on the individual app update button it opens the app instead of updating them. This started yesterday afternoon for me. The iPhone and iPad mini are on 7.0.4 and 7.0.6 respectively and the iPad 4 is on 7.0.
Note, we have two iPhone 6's running 8.0.2 and they update fine. It's not a space issue and restrictions are not applied (if either are your case then try fixing those first.)
I've tried the following to no avail:
- Manually close the App Store and reopen.
- Attempt update over LTE rather than WiFi.
- Reboot device.
- Shutdown device.
- Reset (hold home and power button until powered off.)
- Sign Out Apple ID and sign back in.
- Sign Out Apple ID, reboot and sign back in.
- Reboot my router.
- Reboot my modem.
- Sacrifice a live chicken (no, not really.)
What actually works but doesn't seem to make a lot of sense...
Search for the app that needs to be updated and open the description. Press Update which prompts you for your App Store password... for each app... then that individual app updates (not so bad with Touch ID but still a bit strange.) Not too tough a work around and works until we figure out what's going on unless you have a lot of updates.
It seems to me that more and more people are having this issue which just started up yesterday or Friday. Since it's not just me and it's happening to jailbroken and non-jailbroken devices it appears that the problem is with the App Store and not us... or... randomly affecting certain folks, locations or iOS versions.
Anyone not having this issue?
