Looked at this with the Tech Support team, who were very helpful with troubleshooting and then asked me to report this issue to the beta team.
I'm working on a crime statistics dashboard and have placed the web map on a secondary tab so I have more room for all of the charts. However, when the dashboard loads, the charts will spin forever or display a no data message until I switch over to the map tab. Once the map loads, then the charts will finally load (though sometimes I have to apply a filter and then unapply to get the charts to load).
It appears that the dashboard does not send a query request to the web map if it doesn't load on the first screen/tab. I tested this same configuration in Ops Dashboard, and it does work, albeit the dashboard is much slower since it's an older version. But as such, assuming this is a bug since the functionality exists in the previous version of dashboards?
It's a non-public dashboard currently, so images below showing the charts not loading, switching to the map tab to load the map, then the charts finally loading.
