We have two dashboards set-up with set page filters that cannot be updated by the team. Twice (in two weeks) the page filters changed (apparently by the system) which caused much confusion.
Upon submitting a help ticket, I learned that some automatic updates within Insight Designer could and had changed the page filters and I was instructed to submit an "have more control over filter behavior—such as preventing automatic overrides".
I think this is RIDICULOUS but here we are.
