@Melinda33 the price is changed immediatly.
there are two places where you change prices:
- host / manage listings/ calendar and more/pricing setting/ base price
Your base price will be seen if your guest did not set the exact dates
and
- host / manage listings/ calendar and more/ ... you manually select dates and set "price for the night" and then hit the save button
Your manually set price will be seen when your guest set the exact dates
there are also other options under "pricing settings" like discounts and extra charges etc...
tip: do it on your pc, not iphone
