Hello @Pat10675
Is there any chance that you updated to the new version? If so, there are lots of hosts who have posted on the CC complaining that they can't set promotions, set minimum/max stays etc
The fix is to click on "professional tools" which is now available to everyone not just those that have 6 listings even though Airbnb haven't updated their language on this.
Let us know,
All the bet
