I guess this isn't really a question, it's more of a "can you fix this?".
In either Firefox or Chrome (Windows 10 system) [I didn't try Explorer], when I go to upload a video (click "Create a Video"), if I deviate by adding the description first (this helps me to upload the correct video - the one that matches the transcript content), the upload options disappear (see the attached image), but if I click publish I am prompted to upload a video. The workaround is to open a new video and attempt to create a new video, at which point it asks me if I want to recover the video I was working on. Ideally, if it prompts me to upload the video, the upload options should be available.
