I just signed up to Sparkle. Love the free player but wanted more options so paid for a full permanent subscription. But when I share my account it is not recognised. It just wants to sell me another subscription. Support seems to be non-existent but I emailed the only address I could find. Still waiting for a response. Does anyone know anything more about this? Especially, how can I get in touch with a support person?
