If your podcast is on Spotify, you can now see your stats right here in your Acast Analytics dashboard.
Click the Analytics button at the top, then scroll down to Top Players.
If you are not seeing your Spotify data here, it can be because of two things:
You are on the free Starter plan which doesn't show your Spotify analytics.
You have not updated your show's host information on podcasters.spotify.com (this is only necessary for existing shows moving to Acast).
