License validation error
I installed UAPP on my new smartphone. When I try to use the app i get the following error:


Failed to validate license!

This may be because of a network error. Please make sure you are connected to the internet and start USB Audio Player PRO again to retry"

My internet connection works well, so I don't know how to fix this problem.

Thank you for your help

Problem solved, there was a temporary problem with the Play Store.
