I am trying to import sunets and supernets from an excel speasheet but as soos as click on NEXT to confirm the column association, I see a progress bar that quickly disappear and then the Browser just becomes grayed out and does not do anything. I've lesft it for more than 15 minutes like that without anything getting imported. I even tried downloading the sample file and uploading it right after and nothing happens.
Has anyone ever encountered this behaviour ?
UPDATE...
Was using Internet Explorer. Tried with WaterFox dans got further. The first upload test worked although I was getting a Dialog box saying "Command Failed" " Safe Handle has been closed". a couple of time as I kept retrying.
Now with my second test, I am getting the message all the time.
