Can i delete progress of one of the languages that i started? I mean,can i start from the bottom again?
Yes. If you go the settings, by hovering over the white pointing down arrow, then click "learning language". There should be a grey button under the big blue "see all language courses" button. Click that then select the course you want to remove.
Hope this helped :)
Thank you so much !!
In your settings (your learning language settings precisely), there is an option to remove or reset languages at the bottom. From there you can reset the progress in any course you're taking.
Go to settings, then learning languages and you can reset the languages you want.
You can delete the language and add it again.
