PySide2, Maya 2017, Drag-and-drop woes

Hey there,
I have code that allows for dragging from my custom UI to the Maya viewport that works fine in Maya 2016 using PySide. If I try to use the exact same code but adjust for PySide2, I can no longer get DragEntered or Drop to work. The dropAction always ends up being IgnoreAction instead of Move, Drop, Copy, etc.

Has anyone run into and solved this issue in Maya 2017?

Thanks,
Alec

I have a PySide GUI with a tree view that allows for drag and drop within the UI and it works in both PySide and PySide2. I don’t have anything that drags data from the UI to somewhere outside of it…
