I'm on the other side of 8 weeks for my order. It seems like the combination of COVID-19 and the increased demand for camping, etc. has really slowed things down.
I had the same problem when I bought my '07 Sport recently. Switch it to 4HI then try backing up about 40-50 feet. I'm told it "resets" the system. Not sure if there's any truth to that, but it's worked for me every time I've experienced the same problem as you.
