Tell us what you are trying to do?
We have an infinitive scroll on this page which works fine: hidden link
The problem is even though we have a spinner added to show we cannot see it on screen.
It's not that it doesn't work, but it works only on a very particular setting and circumstances. So it is almost equal to "does not work".
Basically, you'd have to disable caching and preloading of the items, and even so, you might not see the spinner if your connection is - literally - to fast.
We have an internal task to make the spinners on infinite scroll work as we humans would expect it, meaning from the first-second pagination is triggered, and not a slight delay after as it is now.
While these works are done, the feature will be reviewed, and I have added a note to consider as well to not require un-caching and not preloading items, as that is counterintuitive.
For now, I cannot offer any other solution, however, and will keep you updated about the progress here.
Today's update of Views includes improvements to infinite scrolling and the appearance of spinners, could you please check after updating that you can see the improvements?
