I see this comment on GitHub, and I'm guessing it's probably spot on:
I don't see IMDb "fixing" this issue anytime soon to be honest; they probably caught on that a metric shitload of users are scraping their IMDb watchlists from Sonarr & Radarr, generating heaps of traffic that IMDb has to pay for.
That sucks, but it's probably not high on Amazon's priority list of API issues to fix.
Really cool. How did you get the lenses in? Just pressure fit?
