Sorry. According to Spotify, if you didn't have your notifications on by December 18th, you can't get your stats. I do agree with you, that they should've sent the stats through a browser, like before.
Now i managed to scroble in last.fm all plataforms that i use to listen music and now im using much more other plataforms over spotify. Before i tried to listen all i wanted on spotify just to get a more acurate statistics for the year. :c
I'm afraid that's exactly what it means! Spotify basically said if you didn't have your notifications on by December 18th, you were screwed! Sorry. The only hope is if they do a YIM for 2017, they won't repeat this debacle, due to all the complaints they've received over this!
I am extremely dissapointed about this. I've been patiently waiting for my year in review to come up all month and when I finally decide to search for it on my own I find this...
I have all of the requirements to recieve this email. I've had my email notifications on for years. I listen to spotify extensively and exclusively throughout the week. The year in review means a lot to me and so surely you could understand my frustration when I find out that the official response was basically, "Sorry. There's nothing we can do about it. You'll get one next year."
