Had the same issue today. Tweeted to United and got an official response that United will begin selling Premium Plus on Sept. 27 for flights beginning October 2. The free seating in Premium Plus cabin for domestic flights will stop on the said date. But fare buckets remained zeroed out for my flight.
Update: on transcontinental flights with B787-10s
