Internet Explorer Mode on Edgium

Several weeks back I enabled the flag for this mode and the option appeared under “More Tools” in the ellipsis menu. When I tried to do this on my work PC (the only place I need it) I was told that it wouldn’t be able to work since the application was installed in a restricted user mode rather than installed in administrator mode. I got a chance to grab one of the IT folks when they were nearby setting up a workstation, and when I brought him over and was going to show him the problem, I found that this option no longer appeared in the same place. I made sure the flag was enabled but I still can’t find it. Did they move/remove the IE integration on a recent Dev channel release?
