This is super frustrating. I have used it for years and this problem started last week. When I hit 'render as' and try to change the name of the file, which I absolutely need to do as a freelance video editor, if I try and edit the name it makes the file location disappear. If I don't edit the name, it works.
This time problem is taking up a lot of my time. Because then I need to go back and re name it once its uploaded- and its just not ideal. I attached a video showing what happens.
