On my account the tabs along the top blue bar are Home, Activity, Discussion, and Immersion, while on my brother's account there is an additional tab for Words that has a list of words learned and how recently they have been practiced.

I don't know if this was a new feature added on an update but I believe we made our accounts around the same time and don't see how that could be... also the lesson interface is slightly different.

Anyone have similar problems/know why this could be?
