Windy app on my pixel watch 4

[Mark Adams 5]

Hi there

As a sailor I thought the windy app was exactly what I was looking for to get wind information. The wind forecast screen is exactly what I want but although it displays the current wind I cannot make it change to future times either touching the screen or using the crown wheel makes no difference, it just stays on current time. Is there something I'm missing or is it an issue with the pixel watch/app?

Thanks
