Hello,
Thanks for reading my question.
The filter for the dashboard consists of all the standard tasks for 3 projects.
and I have shared the dashboard with all the logged in users. But the group members see bellow errors:
1. The filter used isn't valid or it's restricted
2. The filter configured for this gadget could not be retrieved. Please verify it is still valid on the issue navigator
(Screenshot attached) 
can anyone help me with this issue?
