I just downloaded the latest version from the Poweramp site, due to a glitch with the Play store version, I'm running Android Oreo, and when I tap the skip track buttons on the player interface or the remote buttons on the headphones, wired and wireless, it skips 2 tracks. I've changed no settings in the app. It just started this glitch in the past 2 weeks. Edit- I'm using Moto G5s plus unlocked.
Reducing track progress zone would be a great idea. Maybe by 50%?
