Promotional discount not possible any more?

[Bob40]

Hi colleagues, I saw the possibility of a promotional discount on my apartment yesterday, which since I opened the calendar a week ago after a 15 month Covid pause has not had a single enquiry. Today I can't find the thing. Help simply says 'go to your calendar and select promotions'. Which isn't there. Any ideas? I'm sure I saw it because it talked about giving priority to the listing, which after zero interest in a really popular period, it could do with.

Any help gratefully received.
