mas cannot sign in App Store

[GentleHoneyLover]

Hello,

As of today mas signed out of App Store and cannot sign back in. Until a few hours ago, everything was working perfectly (I'm running mas upgrade two times per day via a script)

$ mas upgrade
Upgrading 1 outdated application:
WhatsApp Desktop (0.2.9739)
Error: Not signed in

Then I do

$ mas signin <my_email>
==> Signing in to Apple ID: <my_email>

Doing

$ mas signout

and then

$ mas signin <my_email>

doesn't help either.

Bug? Any suggestions?

Running the latest macOS 10.13.5

Alas, this is a known issue in High Sierra (10.13) that has not been resolved yet. ☹️

Closing as a duplicate of #107

The only option right now is to sign into the Mac App Store GUI and then you can use other mas commands.
