I called in today to do a same-day standby for an earlier flight tomorrow morning. The agent mentioned that the first segment looked like I would clear no problem, but the second segment might be a little more difficult. I asked her how many available seats they were on the second flight, and she said that she was not allowed to give out that information. I have definitely been told in the past how many open seats there are, so I found that a little odd. I didn't really press it though, because I figured I could just look at the upgrade/standby list on the Delta app

Well now when I look at the app, it is not showing the standby list. it just shows me the upgrade list, as well as how many available seats there are in first class and in economy. I don't remember reading about this elsewhere, is this something new? Or is it maybe just a glitch?
