Can’t sign in, Yamaha doesn’t care. – Soundmondo - US Review

Simply the worst experience with this Yamaha product. The app has never allowed me to sign in and the Yamaha forum moderators are rude to users who have all flagged the same issue. Why this app is allowed to be released by Yamaha and further allowed to be published in the App Store is beyond my understanding.
