Aprox. hour ago all childs of our base dashboard was correctly showing data, but now there is no data shown in them. We didnt do any changes, I checked all dashboards and assigned data sources, and it looks all correct. I checked our databases and if I assign database to main dashboard it works, but childs are not displaying any data.

Hi Markéta, we looked into this with our engineers and applied a fix on our end. Would you check and let us know how it looks now?

Yes, now working correctly.
