Custom visuals shows nothing on the Report server webpage

Hello All, 

I am having an issue where any of the custom visuals i use in the report aren't visible after publishing it onto the report server. It works fine on Power BI desktop(RS compatible) but fails to display the visual on chrome or edge. However It works fine on IE 11, upon opening a case with the support team, the answer i got from them was the browser i use has restrictions on thrid party cookies. 

And i cannot change anything as its a setting accross th organization. 

But these are Microsoft certified visuals (PBI Certified)  infact couple of them are owned by Microsoft like Chicklet slicer & few more.

Any suggestions are much appreciated.
