GST NEW FORM QUERY

FIRST OF ALL I WANT TO SAY , WHAT'S THE PROBLEM WITH OUR COUNTRY SYSTEM. IN RECENT DAYS GOVERNMENT SAYS THEY MAKE SOME CHANGES IN GST RETURNS BUT I LOOKED VERY HARD ON INTERNET BUT NOTHING FIND ANYTHING NEW OR CHANGED. SO MY QUESTION IS IF WE HAVE TO PAY SELF ASSESSMENT TAX ON MONTHLY BASIS THEN TELL ME PLEASE HOW IT IS DIFFER FROM GSTR 3B , OBVIOUSLY IT NOTHING POSSIBLE TO CALCULATE TAX LIABILITY WITHOUT INWARD & OUTWARD SUPPLY DATA . THEN WHY THE INDIAN GOVERNMENT MAKE FOOLING US TO SAY THAT THEY CHANGE GST RETURN FROM MONTHLY TO QUARTERLY BASIS.

PLEASE TELL ME IF U HAVE ANSWER OF MY QUESTION...
