US embassy/consulates opening slots for O-1 appointments

Does anyone knows when will embassy open slots for O-1 visa. I usually find very less information on it.
O-1 comes under a Business/tourist visa ( B1-B2) and what I read so far is that the embassy is not giving any dates for a business visas.
Does anyone else have issues with O-1 stamping?

This will only happen after the travel ban is lifted.
