I noticed that there are some app updates on App Store, so I went to "update" section to apply updates. Then I noticed that "update all" button is greyed out, and each individual app says "open" instead of "update." Earlier today, I couldn't see the list of purchased apps because apparently App Store thought I was in a different country How do I fix this? I don't want to apply "automatic update." I already checked settings for location services and App Store/iTunes Store, and I don't see anything that could be causing this issue.
