221g dropbox eligibility

Hi there i applied for dropbox h1b visa on april 2021 and received 221g due to presidential proclamation and got whiteslip with passport returned. I have been waiting since then to get the appointment and visa stamped but no update is provided from embassy. Can i apply for a new dropbox appointment or i have to wait until regular h1b appoinments start ? Is there anyone like me who recently got visa please let me know
