You should contact Apple for refunds, as they handle the payment processing in the AppStore. How can I get a refund for an in an purchase I made fro SynthMaster Player iOS?.
You have to upgrade to SynthMaster for that purpose. No, everything bundle upgrade contains our presets banks only. Does it contain a licence for the full version of SynthMaster as well? I own SynthMaster Player and planing to purchase Everything Bundle Upgrade.
