New dashboard tiles can't load when loading the dashboard in published application. However, the referenced report visual is loading correctly. The issue is not happening for the workspace author but only for authorized users in the application format.
Tiles are empty with a grey Power BI logo. The dashboard status bar states that the page is refreshing without being able to do it.
I tried to fix the issue doing multiples actions:
Create a new dashboard
Create a new report/dataset
Change the pinned visual
Change the user
Change the application from organisational to private
Update the on-premise gateway,
The only way I found to bypass the issue is to share the dashboard to the user (instead of going through the application publish). Then opening the dashboard in the "Shared with me" menu. Then going back to the dashboard in the application.
