I do cider the same way and mine always clears... If your in a carboy... Do agitate it.... gently... Then make room in the fridge. 20 is cold... maybe if you had to put outside, do it during the day and put a heavy towel/blanket keep the yeast from bumming out in the day light and help slow down the cold crashing part too.
Kegging ? Mine I do like it dry, champagne style... My wife likes it medium, so I'll stop/cold crash a 5-er just as it reaches 1.003.... It will drop a point or 2 whilst serving.. Sneezles61
