German Feedback Wanted

We’ve recently had a third negative review for Folder Sync on the German App Store. We are a bit puzzled about this because we’ve had quite a lot of great reviews from elsewhere around the world. The frustrating thing is that none of the three users who left the reviews have contacted Destek support for assistance. If you are using Folder Sync and purchased it via the German App Store, we’d love to hear from you as we are keen to get to the bottom as to why German users may be having problems with Folder Sync?
