French Fluency Shield?
A French fluency shield has appeared on the right hand side of my screen my my French tree. Has alone any idea whats going on with this or how the fluency is calculated?
It's a feature that has been in A/B testing for the last couple of weeks that is being rolled out to everyone. It's only available on certain courses, so, for example, you'll see it on your French tree but not on your Esperanto one.
