Good evening, first of all, I apologize if I am using the forum incorrectly as I'm unsure if this subforum is the right place for this type of question. I would also like to apologize in advance for any mistakes I may make while writing in English, as it is not my native language.
Regarding my question, let me explain it below. Some time ago, I purchased a Poweramp license for Android through the Google Play Store, which I currently use daily on my device to listen to music. However, a few days ago, I acquired a Fiio M9, and since it doesn't have the Android app store, I understand that I need to purchase another license, most likely through the website based on what I have read (please correct me if I'm wrong). Once I have the license, another question arises: applications on the Fiio are installed through APK files, and I would like to know if I would lose my license when reinstalling the APK with a new version to update the app. In other words, if I buy the license and use it in the app, am I required to stay on that version, or can I update the application by installing the new APK version without losing my license?
Thank you in advance for your help and understanding.
