I get data for 50 items, the request is very fast and the progress does not even have time to appear on the screen. During the scroll, when there are 6 elements left, the next 50 are loaded to the end and progress also does not have time to appear on the screen. Is there any reason why I should still show progress?
Actually i would implement it, because, if somebody with slow connection gets connected, or somehow the query needs more time to process, the user will be at least prompted something.
I think it's a must for UX.
