United T-14

Hey all, first time I’m booking award travel. A few weeks back, I found a nonstop Polaris seat ORD to LHR for 110k points on the day I was looking to leave. I couldn’t transfer my UR points fast enough. I have been reading on here that sometimes United releases seats at T-14 (assuming that’s calendar days). I have been looking at flights in the United app for other dates that are within today’s T-14 just to see what points look like. All I’m seeing are like 295k flights within the next 2 weeks. Does United not do this anymore?
