Web app keeps switching language after reload#4433

Hi Tiimo team,

I would like to report a language issue on the Tiimo web app.

I have already set the app language to English, but the web app often switches parts of the interface or content back to Vietnamese after I reload the page.

This makes the experience inconsistent because I prefer to keep the interface in English, even when I write or interact in Vietnamese.

Could you please check whether the language setting is being saved correctly on the web app?

Thank you.
