Same for me - I got fed up of using JustWatch to check which (if any) of my subscribed streaming platforms had the film I wanted, open said platform, search for the film, find out it's not actually available (or I have to pay on top of my subscription), and rage quit.
I even looked for a way to use lots of streaming platforms from the same interface, but of course you can't do that cause DRM/lockin/etc.
You're tearing me apart Lisa!
