Same here.
I am losing almost all 1|0 games with the other player having 10 to 32 seconds on their clock, and mine run down to 0. Making premoves does not seem to help.
Using latest version of Chrome browser, without extensions and removed browser files. It does not help.
Too bad...
Sometimes after the first few moves of a game, let's say 3, I am down to 55 seconds in a 1|0 game. All of my moves were premoves, so I don't understand how this could happen. Perhaps it has something to do with lag? It seems that this even happens when I chain my premoves.
