JustWatch data incorrect?

Has anyone noticed that the streaming availability feature has been more unreliable lately? I just went to watch a movie that LB said was streaming on Hulu, but it’s not. This has happened to me several times recently and I’m not sure what the issue is. Maybe it takes a few days to update at the start of the month when titles rotate in and out? Still annoying because now I have to pick something else lol.
