Thank you very much for the explanation and the link to our webview version - turns out I had to access my full profile settings from my Firefox browser there. I was able to select “English” and also “Deutsch” (= german, my native tongue) together with the standard “Undetermined”. Unfortunately it couldn’t be done from my current app, but it worked pretty conveniently on my phone browser. Android phone with A 15 and the latest Firefox version for anyone wondering…
