Bastien, when you go to your listing on the app, you then click on Booking Settings (at top right of screen). Then go to the very bottom of the page under STATUS. Then click on SNOOZED and it will allow you to choose dates. I hope this helps you find it. I have to relearn it each time...
VERY IMPORTANT: I just found out today that the snooze feature doesn't work beyond 6 months from today's date so if you want to snooze well in advance, you will want to first block dates and then as the dates approach you can change these to snooze. The advantage of snooze is it won't affect you once you have superhost status (but this takes a while to get enough guests to qualify).
