Recently, I've enrolled myself as a GST Practitioner and have been authorized by the client for the said purpose. But, while trying to file return from my GSTP login, I'm unable to submit & file return and a dialog box appears as "You are not authorized to file the return".

Advice on the aforesaid matter will be highly grateful.
