Was on the mobile site today. iPhone 11 - 13.6.1 Safari.
And it’s not so useful when looking at a particular ride.
Here’s a video but it’s not showing up in the preview so might not work.
What’s happening is that the graph at the top of the page showing power, elevation, hr, cadence and speed doesn’t scroll. It hovers over everything on the page. You can see the info scrolling by above and below the graph, it’s just all covered up.
