I have been using Youtube Video Downloader for some time and it has been working great until a few days ago. I emailed the developer, yesterday, that the download button is missing. Dishita sent me a reply within 2 hours explaining the problem and that Youtube has made some code changes that caused the problem. Dishita said they are working on a fix to be released soon. This is great customer service that Dishita replied so quickly with the reason for the problem and letting me know a fix is on the way.
