Why are dashboards with "preferred_viewer: dashboards-next" loading legacy dashboards as of yesterday [10/28]?

[minerkt]

As of yesterday [10/28], when I open a dashboard that has the “preferred_viewer: dashboards-next” parameter, it takes me to the legacy dashboard experience which does not handle a lot of my formatting.

I am still able to manually change the url by adding the “-next” tag and loading it in, however this is not helpful for anyone using my dashboards.

How can I have the dashboards-next load automatically without changing admin permissions?
