I changed my duolingo native language to Arabic.
I wanted to learn this language and with a mistake I changed the entire site's language to Arabic. also, I can't see my progress in spanish anymore and I think I lost the progress because of that. hope that you can help me :(
No you didn't lose your progress. Just switch back to English. You'll get your progress back.
I accidentally did likewise, and had to use Google Translate to get it back - I eventually did, although I'm sorry that I don't remember how.
