why do you get bonus lingots for completing lessons with a sansung tablet?
You do? Didn’t know that. I guess doulingo doesn’t like Apple, and is rewarding users for using a different brand!
The weird thing is getting bonus XP when getting everything wrong.
I think the extra lingot is with each crown?
Nope, it's also with every lesson, if you don't make too many mistakes. And I have it on phone and PC - both not Apple.
