Misbehaviour of Welcomebot and Restricted Direct Message Setting in Server

Sorry, typo - I have 1.2.0 installed. I somehow confused the version number with the version of another installed plugin.
Marketplace says that the WelcomeBot plugin is up to date.

Yes, WelcomeBot is activated for the team in question.

I fear that probable most instanced don’t have "RestrictDirectMessage": "team" enabled…
