same problem While filing GSTR 3b it says that "Last GSTR3B Save request is under process..." since 6 hours as per attached screen short what to do now.????
I am also facing same problem. Seems a bug in code and not an overload issue. While I am getting this error for one of my logins since last 2 hours, during the same time I have been able to login and submit return for another of my companies. This needs to be reported to GSTN.
