Hi, I am trying to change my current guest's reservation. He woul dlike to extend his stay by one night. I'm not sure if this is a technical issue as I was not able to even begin this process on my phone on the Airbnb app. So I'm now on my laptopn trying to extend his stay. I can request the change but no button pops up to say "Submit" so nothing is happening further or after the page where I request the date change. Th eonly click button that come sup is one to cancel the change which I don't want to do. I don't wan tto bother my guest by asking him to do this from his side but I can't submit the change for his approcal. Help!
