Scrum board custom column not visible to other users

[Fabio Formosa]

I've added a new column to scrum board ("test") and it's mapped to the existing status "test".
I can see the new column in the board, containing same issues in test status, but other users don't see it.

I've not found any settings about permission and visibilty on scrum columns.

What's wrong?

I found the solution in my own.

Other users access to another board than board I access where I customized the columns.
I've noticed this, looking at ID of rapidView query param of my URL and URL of my colleagues.

The boards don't have permission settings, they got permissions from custom filter query related to them.
The filter query applied to board with customized columns was private to me.

To solve, I've just shared the filter query with all user in project.
