Dear Madam or Sir,
I bought the app on Google Play with my account ///////////////////////. Nevertheless, neither app nor website show Premium features. I'm being forwarded to the subscription website. And even if I'm trying to solve it by buying it again, Google Play simply tells me that I do have an active subscription already. This is pretty frustrating :-(
Kind Regards,
Gernot
