Not able to see open slots while others can see


Today there were so many H1B dropbox bulk slots were open for Nov,Dec 2022
The slots were available for about 30 mins, but I couldnt see any of those in my account, while others were seeing many open slots.

Suspected reason : My last stamping was in early 2022

Not sure if the reason is right or its a server glitch.

There were many other people who confirmed that they too have not seen the slots and the common case among us was that their last stamping was also in the early 2022

I have the same case and seems the same reason.What does that mean, Do i need to wait for next year.I can see slots only for next year September 2023 and so on.
