Called today and had a pretty candid conversation with a supervisor that was trying to help me add a 3rd or 4th seat to my tickets in the lower level. He said unless someone who has already paid calls and just cancels their tickets he does not expect many more open seats in the lower level. There were however open seats in 229 and 230 groups of 3. There are of course multiple single seats available in the lower level and there are some 100 level seats with like seat 30 in row 11 and 12 in the 100's if you were willing to sit like that.
My initial ticket operator was not very helpful and transferred me to premium tickets who said this is a mistake you shouldn't have been transferred here, I asked for a supervisor and the next guy I talked to really went over section by section with me offering me options to get me an additional seat in the lower level but I did not like any of the options so I dropped it. (I wanted to add 2 seats together not just an extra ticket away from my seats)
(if anyone wants 1 lower level ticket in 200 or 100 message me and I would be willing to purchase it and then sell to you)
Edit I left out he said anyone with lower level seats should expect that your upgrades would have already been posted. There are no expected 2nd waves of lower level seats, some upper deck seats are still getting updated in the machine but no one else that's already in LL would be moving past this initial round
