I have a basic price of $100 a night. I do not use Smart Price . I oticed on my listing a added button Reserve for $75. I have had someone book for $75 a night and I'm not happy. I didn't authorize this. Then I had a person message me that it showed $50 a night but when they hit the Reserve button the price did go up to $100. Then they weren't happy. What's going on? I don't want my base price changed. How do I prevent this from happening?
