Lightning Experience Pass Parameters to reports issue

We have created a custom report with a filter to say Account.id = "" (blank), For Dynamic reference for different Accounts I created a custom button with the URL as {!URLFOR($Site.Prefix+'/00O0y000006pQZqEAM?pv0='+Account.Id)} this was working perfectly fine in Salesforce Classic when a user clicks on the button from the account page it used to apply a dynamic filter of account id and shows data as per the specific account. After moving to Lightning I have replaced pv0 to fv0 on the button URL but now anytime a user clicks on this button it isn't applying any filter the report data is still filtering out as Account.id=blank. Please let me know if anyone else has faced a similar issue? Our user depends on a lot of such dynamic report on the record level. This affecting the ability of our users to work efficiently. #NeedHelp
