⚠️ Gumroad Service Termination Notice ⚠️ I sincerely apologize, but due to ongoing issues with Gumroad — including frequent product deactivations, account suspensions, and unauthorized withholding of payments — I had no choice but to deactivate all Gumroad links and remove all products from the platform. Only Sociabuzz is available for now, and tutorial-related files will be uploaded in the near future. sociabuzz.com/dad_piano/shop I apologize for the inconvenience and kindly ask for your understanding.
