I'm creating a new post for this as the existing post are almost 7-8 years old and there is no clear answer on how to do this :-)
The following assumes Youtrack 2018.1 is used, multiple projects with a specific team group per project are also there.
Creating a new ticket from an Agile board set the visibility of the card to "All users". My expectation is that the default visibility should be set to the project team (so no action from the user for each new card).
Is there a way to configure this? (hopefully an automatic configuration that matches the default visibility of each project to the default project team).
