Can't drag RBXM files into studio anymore

I’m used to being able to open rbxm files by dragging the file into the studio window. This doesn’t work anymore. Less than 24 hours ago it did work.

edit: tried it again and now it does work. not able to tell what the fail conditions are.

I recall that when I encountered the issue, I downloaded the rbxm file first and then went to open studio and it began updating itself. When it finished updating and I opened an empty place, it would not let me drag the rbxm file into the place.
