Every time I restart my Mac the App store asks to log in again
Since I've installed OS X Mavericks I'm getting this really annoying pop up to log in again to the Mac App Store every time I boot up my MacBook Pro and log in into my account. Is this normal? I've searched the web but didn't find anyone with the same problem. Any advice? I tried logging out completely from iCloud in my account but it didn't work. Automatic updates are on and I'm running the latest version of OS X.
MacBook Pro (15-inch, Late 2016), macOS Mojave (10.14.1)
