i am an user from china. I purchased Poweramp from the website, account is:
Later i found that i cannot connect this email to my android account. So i purchased again via another email.
when i try to unlock by "website" button. It said the account is not connected to my device (actually i already connect the second email account and sync is enabled)
when i try to unlock by unlocker. It pass the certificate at the beginning. However, failure of authorization pop up a bit while later.
My device vivo xplay 6. version of Poweramp is 703 alpha (have to use the alpha version since 5xx do not support dsd files). The version of unlocker is 1.0 ( dont know how to get a new version of unlocker)
I purchased 2 accounts and both of them do not work now
