Uploading Files with Safari gets stuck or fails

Quick Fix:
Use another browser such as Chrome or Firefox

More Info
Using Safari to upload file can sometimes fail, even if you're trying to upload a valid file. This can occur on both the desktop and mobile (iOS) versions.

This is a problem that appears on other large sites (e.g. - Dropbox & WeTransfer ). The source of the issue appears to be a problem in the Safari browser itself. Because this is a browser-specific issue, we can't give an exact time estimate as to when this will be fully resolved.

If you're using safari and the file upload isn't working, we've found you can sometimes bypass the issue by unselecting and re-selecting your file.

However, a longer term, more robust solution is to use another browser, such as Chrome or Firefox, as these browsers do not exhibit the same issue.
