Streaks no longer public?
Sorry if this has been discussed – I couldn't find it. Are the streaks no longer public on your profile? I kind of liked seeing it there, for me as well as on other profiles.
You're right. Users who were switched to the "achievements view" can't see another user's streak and location info, and can't block them. One workaround I found is to open other user's profile page in a different browser on which one is not signed in to their duolingo account.
The achievement view is the name I use to call the new profile page appearance that duolingo has implemented for some of the users (so it’s an A/B test). A user that has been switched to the achievement view will see on their profile page a collection of badges that show different aspects of that user’s performance. Also, the user will start to see other users’ profile pages differently (as OmegaGmaster and I explained).
This is how the badges look like (the performance of the badges in the red frame will be different for each language that the user is learning; the one in the picture is for the Spanish tree that has 61 skills):
