I completely agree. We are near the US Canada border, and our guests come from both countries equally. The Americans see the American reviews first, and the Canadians see the Canadian reviews first. This makes no sense because guests aren't going to keep scrolling past a page or two, so they miss out on the really great recent reviews from the other country. If we have several American guests in a row, Canadian travelers aren't going to see those reviews and will think no one has stayed in our condo for months. They'll never see the great things the recent American guests have said.
Like most hosts, I'm always working on improving our guests' experience, and that's reflected in the most recent reviews. Reviews should be in order regardless of the traveler's country.
I have submitted a feedback form and would encourage others to do the same.
