I am on Android 10, MiUi 12.0.2. Tor Browser 10.5.10 (91.2.0). In my phone settings, if I set the country to India, Tor Browser User agent has Accept-Language: en-US, en-IN, en. This is not seen in Desktop Tor.
Wouldn’t they have to be aware of it in order to close the ticket? It doesn’t look like a fix will be implemented any time soon. Your best option is to set system language to English and browser language to English. The bulk of development goes into desktop, sadly.
Yep, and it has been added. In Settings > Language at the top there is a toggle to “Request English versions of web pages”, turning it on spoofs the accept-language header.
