List of Prime Video movies not refreshing in IMDb (unknown for how long)

 

However when you click the blue button to jump to Prime Video, it's only available as a paid-rental within the United States.  I double-checked my Content Settings in case there was a country mismatch between IMDb and Amazon (see below), but even after forcing IMDb to show content as within the "United States", it still shows as available within Prime Video, and I know my location is known within Amazon.  It seems to me that IMDb is currently not absorbing the database of content currently available within Prime Video, and it's not apparent how often content has either been added or removed, since this movie isn't that notable enough to draw attention from sites monitoring Prime Video for additions & removals. :-)
