With the last update on Version 23.12.1 (1a1d4d54), Python 3.9.15 Qt 6.6.1 PyQt 6.6.1 the tip of the shared deck Duolingo Spanish for English speakers (247695077) doesn’t work anymore.
The search term for this filtered deck would then be something like -tag:::21* -tag:::20 -tag:::1 -tag:::0 "tag:* Spanish::" is:new if you are already familiar with lessons 1-21. Now just prepend -tag:::22** if you want to ‘add’ lesson 22 back to your language deck.
If i would to learn Languages::Spanish Anki, Anki now shows me cards of the filtered deck.
So isn’t this featured anymore or is it a bug?
