Not able to save dashboard theme

 Hi sonam7 ,

There are some limitations you need to considerate when using the Dashboard theme,

1.Dashboard themes are currently not supported when viewing the dashboard embedded using the REST API, on mobile devices, or by external users. 

2.Dashboard themes cannot be applied to pinned live report pages, iframe tiles, SSRS tiles, workbook tiles, or images.

3.Dashboard themes can be viewed on mobile devices but creating a dashboard theme can only be done in Power BI service.

4.Dashboard custom themes only work with tiles pinned from reports.

You can learn more about Dashboard theme:https://docs.microsoft.com/en-us/power-bi/service-dashboard-themes.

Best Regards,

Amy
