Hi Parthi,
Sorry about the inconvenience you are facing.
I see from our end, that you withdrew the app from review last. If you are still getting the 'Your session has expired". Then can you try clearing your cache once and try again. Usually we see this error when the user leaves the webpage open for a while and the session times out.
Can you also confirm on the app submission page that there are no errors. Please share a screenshot if you are still stuck.
I’ve tried on multiple computers too so I can confirm that this isn’t a local problem but likely an issue on the Zoom Marketplace side with my account.
