I did not realize the bottom button was the “Apply”, thought you would toggle Use rolling cache and swipe the screen away.
Also, would have sworn that the other day after toggling Use rolling cache, that Export to downloads option remained in the window. Today it disappears as soon as I toggle Use rolling cache.
I apologize, had not tried the export. When that is toggled, Use rolling cache disappears, and the bottom button indeed changes to “Export” as you say
