Red Dirt Queen Digital Design review for Digital Downloads

I've used this app for years with no problems. With the last Shopify settings update this app no longer works at all. I also had it installed on some of my client's websites I designed because it never gave me trouble before and it was free. DO NOT DOWNLOAD because Shopify support told me they would not be fixing the app. Now I have to download a new one and reupload over 1,000 digital downloads.
