Hi @ezbarretos
Please make sure that all the apps (Dashboard app, Maps app, Line Listing app, and Data Visualizer app) are updated to the latest update. After that you might want to clear application cache and reload apps … and test by checking out the dashboard again using the Guest mode of your browser.
If it doesn’t work, please check if these issues are caused because of missing the cascade sharing: Dashboard saving - Error - After upgrade to 2.40.x - Any thing changed? - #2 by Gassim
I hope this helps! Thanks!
