Android Sonos app 7.2. Samsung S7, recently got upgraded to Android 7.0. Also just received a security patch (both automatically via Verizon)
Now when I grab the Thumbtab on the player timeline to move it, Sonos advanced to the next track! I use this feature all the time, e.g., to skip over advertisements in podcasts or to rewind a few seconds to re-listed to something that was just said. This is a major hassle.
