RS Drums review for Digital Downloads

App was working really well for about a year. However, for the past couple months, it's been extremely buggy, and Shopify seems to have no solution. It says 'Unsupported' under the settings page. Files don't upload for me anymore, or they upload but I'm not able to save changes. One of my products has 2 digital files attached, but the app only lists 1. I'm not sure if things are getting sent out properly either. I've tested different browsers, different computers... Nothing... So it's basically become useless, and I'm at a point where I need to migrate to a new app. Pretty frustrating...
