Help help help – Guitar : Play & Learn Chords Review

I bought the full version of this for one year and after not using for a few months I attempted to login and I can’t get in. I can’t reset password nothing....There appears to be no customer support as all links on App Store page just reopen the App Store page. Do not buy this until it’s fixed. Developer please respond!!!
