I am on v3 703 alpha. What is working for me:
Last.fm app
Nothing enabled in Poweramp scrobbling settings.
And under headset/bluetooth enabled Metachanged intent. (if I disable it, it only scrobbles first song and then keeps showing now scrobbling the same song even thought another song(s) are playing.
If I check Send Album - Artist under headset/bluetooth, it messes up scrobbling adding albums to scrobbles. So in car via BT I see only title, but it scrobbles correctly.
Previously I was on latest v2 scrobbling via SLS while having enabled SLS scrobbling in Poweramp (while having enabled Send Album - Artist under headset/bluetooth) and everything was working just perfect. But I had to switch phones and v2 was playing sort of messy audio on new phone (Android 7.1.1) so I switched to v3 and audio playback is now fine and scrobbling after much fiddling around too..
