API Key Reset Request
Dear Support Team,

We have unintentionally exposed our API key.
I've attempted to reset it through the settings, but it appears there isn't an option available for that.
Can you kindly assist us in resetting our API key?
I apologize for any inconvenience this may have caused and appreciate your prompt assistance in resolving this matter.
Best regards,
Malao

On this page of your profile
https://www.themoviedb.org/settings/api
there is an option in the menu: "Regenerate Key".
Did you try using it and it didn't work?

I didn't see this option. Thanks so much! Will test and use it :)
