Just ran into this problem too and it's absolute nonsense. Why did Squarespace do this and are there plans to undo this in the future? We need reasons, not "that's just the way it is", especially when we've promoted our products with specific URLs and suddenly they're changing. It looks sloppy, it looks like nonsense, and it doesn't give us a way to fix it. Please answer WHY not just that it happened and there's nothing we can do about it.
