You should set up all your social media accounts in English as the default language. This process is easy to do and requires a few simple steps.
You may prefer to set this to your native language, but this process is needed. Otherwise, TexAu won't work in your preferred language.
It's a setup located in your social media platforms' settings & privacy preferences. Usually, you can find this next to your profile icon in the menu bar.
To do so, you can refer to the official help pages of each social platform.
