I was wondering, I have been using this endpoint for a while now and all of the sudden I am getting an invalid API Key response: "[{"status_code":7,"status_message":"Invalid API key: You must be granted a valid key.","success":false}", but this other one works with my same key. Is there something I am missing here. I have listed the end point that doesn't work (but has been working for a long time) and the one that does work below:

One that doesn't work: https://api.themoviedb.org/3/movie/now_playing?apikey=MY_KEY&region=US

One that does work: https://api.themoviedb.org/3/movie/550?api_key=MY_KEY

Any help would be greatly appreciated! Thank you!
