You need to go to your Discover Weekly playlist in your Desktop Spotify. Put your mouse pointer over the title and right click it. In there, the option will appear to 'Copy Spotify URI' and paste it here.
This should be fixed now. As of today, you should be seeing a fresh Discover Weekly.
Let us know if you're still having any hiccups, and we'll continue to help out. Otherwise, happy listening!
Try streaming more this week, and see if next monday you get new recommendations. If you don't, I'll ask for help. :)
Let me know how it goes.
Try logging into your Spotify profile on your browser here with your email. Your username will be displayed after you login.
Logout of your account in the app and be sure to use that username, instead of your email address, to login to your account.
If that doesn't do it, you should try deleting and reinstalling the app. Hopefully that'll fix the issue.
Check out what I get when I access your DW you provided (don't mind the french in the description)
Hope it helps. :)
