It’s weird because there are two Azure versions, and the "2025-10-01-preview" one actually works. If you're determined to use Azure, you should switch to "Azure Translator 2025-10-01-preview" in the community presets for now, until the other one is fixed. It worked when I tested it.
Shoot, sorry, my bad, I must have done the testing on the Preview version like Norby suggested.. I have fixed it now, I should be uploading a new version tonight. :)
