Amazon Prime Video App on Apple TV changed my language « on the fly »

Pretty simple,

I am using an Apple TV (last gen) to watch Amazon Prime Video, through the app on the device.

today, as I was searching for a movie to watch, the app changed my default language (English - or maybe French, but that’s not the point) to Dutch !

So, I have nice descriptions of movies I Dutch... a language spoken only in The Netherlands, northern Belgium and Surinam: nobody speaks that language and it seems to have defaulted on Dutch because I’m in Belgium for the moment.

that’s very annoying and I hope there a solution. I will not give stars or anything to à system or an app that changes the language without even asking.

thx for you help, if you can help me avoiding the nightmare of not knowing what ‘I’m gonna watch (I have an app, I’m not gonna switch to imdb back and forth...

take care and wear a mask !
