Hello!
We're using a Jira Service Project to manage localisation requests.
Inside the project I've created a Kanban board so that it's visually easier for our translators (they have agent access to the project) to see the backlog and deal with it.
I've added the needed JQL query and it works as expected to me.

However, the board only loads for one other agent. 13 other get a blank window with some "kanban board shadow" and it won't load further. They've tried the usual log-in / log-out and computer restart methods already. I've also looked into the board settings a couldn't find any restrictions.

Could you please help us get it working properly?
