Bonus Skills ?

[ktruex1]

How do i get the bonus skills? the three slots showed up in my tree, but when i click on them it takes me to the store where i should be able to but them with lingots, but it's grey and i can't click on it. it also does not show how many lingots are needed to but the skills

Have you filled in everything on the tree before the bonus skills? Because you need to have the basics in order to have enough of the grammar/grammatical words to be able to do those lessons, and it won't let you buy them until you have done that.

The bonus skills didn't even show up until i had completed all the lessons before it and one after it. After looking at it again on the mobile app, i can see that these lessons are 30 lingots. That wasn't showing up on the desktop site
