In my company we have 6 different development teams, 1 UX team and 1 Operations team. 5 of the development teams work on front-end issues and 1 just back-end issues.
We have 1 scrum board configured for each development team showing all the issues involved in their sprints. We have a filter for each board that shows:
- For the 5 full stack teams: issues from their own project + issues from UX team project
- For the back end team: issues from their own project
With that configuration board Insights worked like a charm in each one of the scrum boards.
Last week we decide to also include operation issue in the development sprints. Therefore we change the filter to show:
- For the 5 full stack teams: own project + UX project + Operations project
- For the back end team: own project + Operations project
With that change in the filter board Insights stop working in the 5 full stack scrums. A message like this appears:

Despite adding the same filter to the back end scrum board, their Insights are still visible.
I've already checked if it was a permissions problem but all 3 projects involved in the filters (every development project, UX team project and Operations project) are configured to give the right "View aggregated data" to any logged used.
So, my question is: is board insights limited to filters including 1 or 2 projects?
I did not find any information in the documentation about that. In fact, the error message suggests that insights should work only if you have 1 project configured, but it has been (and it is working for the back end team) with 2 projects configured, which is even more confusing.
