I was trying to upload a video to deliver an order (568MB, max size is 1GB so it should be fine) and when getting close to the end it just resets, happened to me twice. I don’t know if it’s a bug or what. I will try one more time, since I have time, I will refresh the page etc. If it doesn’t work I’ll update the results here and use dropbox.
Sorry if this has already been discussed.
Update: It has to be a bug, it did reset again. I uploaded it using another website and no issues.
