AppStore doesn't work after Mojave update
I updated my MacBook Pro to MacOS Mojave and AppStore doesn't work anymore. When I try to download something, I see the error message "Your purchase couldn't be completed. Canceled." Sign out button doesn't do anything and view my account button gives Couldn't connect to AppStore error.
Anyone who knows a solution or experiencing similar issues?
What country are you in? And what happens if you try to visit a link like this one to Ulysses? Does it appear on the web? Just trying to narrow down if you have a Network issue or an App Store-specific issue. I know @johnfbraun has solved the latter a few times with various .plist file maintenance.
