Hey @isabellaaaaa 

Currently, the September top list can only be accessed via a direct link:
→ https://www.deezer.com/smarttracklist/monthly-top

I'll link to @Yula and @Jaime. and @Alfredo.

Maybe one of the three can say if and when the top list will appear on the home page.

Hello @dee_dirk I contacted the developers and they told me there was a delay with “my top September” card in the homepage, which has already been fix.
You should be able to see the card (which replaced my top summer card) in Made for you in the homepage.
Thanks :)

Thank you @Jaime. 

For everyone who is now missing the "Top Summer" list: This can still be reached via direct link for a while.
