Loss of all my results after adding a language that switched the interface to english

Hi there, I have been using the app for over 3 years for primarily learning/rehearsing German and Spanish from French (I am French actually). I just added Romanian with required the interface to switch to English. The issue is that it all erased my progress in the other languages and I see myself starting from zero again. How can I keep learning both German and Spanish from French, then Romanian from English and switch inbetween? Thanks much, Henry

Duolingo can only portray one user interface language at a time. When you change back to German from French or Spanish from French, your user interface will be in French again and you'll see your progress in those courses (but you won't see your progress in Romanian from English).

The web portal supports the quick "language switcher", even between courses from multiple base languages.

Just click the language flag left besides your avatar at the top blue menu.

As your profile shows nothing is erased.
As Lrtward tried to explain, the other courses are just hidden.

The mobile apps do not support the quick language changer, which was introduced in the Scala web portal rewritten code since February 2017.

If you juggle with multiple languages, it might be better to use a computer with a hardware keyboard. You will learn more - include your made typing errors - than just to click on the word banks with tapping.

If you change the language on the Duo website, they will also get changed on your mobile app when you start it the next time.

There can only be one course active at one time across all connected devices with the same user account.

Gentlemen, Thank you very much for taking the time to support me. I indeed only am/was an adamant user of the mobile application, but will benefit your guidance on the website portal which I never used (or so little) before. Hopefully someday, the switch can be made on the app as well. Again thank you. Cheers, Henry
