Shouldn't ranked decay be turned off right now?

Have been getting messages for the last week telling me that if I do not play solo que ranked, that I am going to start decaying and losing divisions/tiers. I thought ranked decay wasn't supposed to be enabled during the preseason? Because i cannot even play ranked right now and I don't want to start dropping because of something that was out of my control. Just thought maybe someone could clarify what is going on for me?
