You can choose future months from the date drop down in the top left corner. This catches lots of people out but I haven’t thought of a good solution yet.
I tried “infinite scroll” up by pulling down when at the top of the page. It works but it’s a real pain when you just wanted to go back to the top and suddenly an empty month of data appears. I might try fit a button (“Show Newer”) on something on the actual calendar when you are at the top.
