While I would like to just install power amp on all my devices from my Google account (as I should be able to, and as the terms state I should be able to), I can not as Google play stopped supporting any device prior to android 8.0. Licensing of any application through Google play prior to 8.0 now fails due to Google's lack of support. Sad world we live in when the larger organizations drive older products out of play for sales alone, and developers don't stand behind their terms by using an alternate library for licensing. And while I realize I can purchase direct from your website you to, it seems, have followed suit just to drive sales up.
