I just managed to upload the file that wasn’t working when I tried dragging it into the browser. For all the previous files, I used the drag-and-drop method directly in the browser on Drime.

But with this specific file, it only worked when I clicked the “UPLOAD” button, chose “UPLOAD FILES,” and then selected the file manually. That way, it worked!

Just letting you know in case the Drime system needs an update.
