It's best that you contact Airbnb support for they have a way to check the reason why your weekend pricing is not updating. Updating your pricing preference should be real-time.

It states that:
- Weekend pricing does not work if you have Smart Pricing turned on. To override the Smart Pricing price for any night, change the price directly in your calendar.
- Any custom weekly and monthly prices you set after turning on weekend pricing will not be overridden.
- If you turn on weekend pricing after setting custom prices, weekend pricing will replace all Friday and Saturday nightly prices on your calendar.
I hope this helps, Goodluck!
