EDIT: This behavior has reverted back to normal, so I will chalk it up to UA website gremlins.

Hi FT,

I've never seen this before and a search did not seem to yield anything useful, though if this is a common occurrence I apologize for the duplication...

I booked an E+ seat (I have a subscription to E+ since I'm a lowly MP Silver flyer who happens to be quite tall) on a flight from DEN-LAS in 10 days, and it happens to be in the middle. Not ideal, but I've usually had luck checking back periodically to see if seats on the aisle/window open up as the date of travel approaches.

Oddly enough, when I looked this morning, ALL of the E+ seats had been converted into E-. There appear to be only F and E- seats now, which is frankly rather annoying since I chose this flight because my first option had no available E+ seats left. I tried logging out and back into my account as well as using an incognito window to view the open seats, but it all shows the same thing.

The aircraft is a 737-800...am I just out of luck? I am thinking it might be a website glitch and will check back later, but if it's not, I'm not sure if I have any options apart from paying a $200 change fee to get onto a different flight with open E+ room.
