Dashboard missing data range

[twice2ice]

I have a Looker dashboard that functioned correctly for a week. Now, without any modifications, it's exhibiting data range issues. Specifically:

Charts filtered by 'Today' as the default initially display no data. I must manually re-select 'Today' in the date range filter for them to populate.
Similarly, charts displaying the entire data range also show no data initially. Again, manually re-selecting the date range corrects the issue.
However, this fix is temporary. Upon refreshing the page, the dashboard reverts to displaying no data until the date range is manually re-selected.
Essentially, the dashboard seems to lose its selected date range upon loading or refreshing.

Hi @twice2ice   

Was there any change in the time zone of your specific project or Looker instance? The presets work on the default time zone selected for the connection/project.

Is there any date controller in your table? If so, please make sure it’s set to the correct date range. All reports will apply the date based on the date controller.
