In the post you quoted, it states that yobit is still on the old chain.
It is a known issue at this point and all we can do is wait
UPDATE
Until all exchanges have updated to the new wallet, DO NOT send coins from 2.1.1 wallet to exchanges. I will let everyone know when I have received contact back saying that they have made the switch.
I have an upgrade request in to support, but am still waiting on a response. I apologize for any inconvienence while we are waiting, but sadly there is nothing that can be done on my end.
After checking coinexchange.io their wallet is still under maintenance aswell...
This coin was moving around darn fast with only 2 confirmations until you mess it up.... just saying, I have few transactions to yobit no issues, what old chain, there is not old chain, sound like bs
