Not all languages show on Discussion tab
I think I might have found a bug - I noticed that not all languages show on the Discussion tab, only the language you're currently working on. All languages seem to show on the Home, Words, and Labs tabs, but just not the Discussion tab.
Exhibit 1 (Discussion tab):
Exhibit 2 (Other tabs):
If this is deliberate and not a bug, sorry for the post.
AFAIK when you are on the "Discussion" or "Words" tabs the old Scala web portal code is executed.
Only the "Home" and "Labs" tabs are on the new Scala 2017 web portal code.
The new "Duolingo change course" switcher was incorporated only in the new Scala 2017 web code.
If you really want to change your courses on these two web tabs across multiple base languages you need to install the older Tampermonkey (Python) user script for the web called "Duolingo course switcher - updated".
Thanks for the insight. I believe the Words tab is also on the new Scala 2017 code because both courses appear there as well.
on discussion it only shows languages from the same base language (so for example if you learn ES from EN, FR from EN, and EN from ES it will only show the first 2) and apparently they're sorted by the time you last practiced that language
on the main page it shows all languages sorted by level (first the ones from the base language tho)
