I have reported the same issue back in May 4.  The next day, they came back saying they added the issue to their list of tasks, and that they don't have a firm timeline to fix the issue.  I'm pretty sure some others reported the same problem as well.  I hope they fix it soon.

I hope so too. I like the showcase feature.

yeah I'm missing mine as well

mee too. i just got a sun badge and want to show it off, but i used to have one, but now i don't. me confused

That is probably because, like I said, showcases are not working right now. However, I happened to notice you can see the showcases of people who didn't have any badges in it when the feature went down.

Hello everyone,

I wanted to inform you that the Badge showcase is currently facing some technical difficulties. 

I've shared your reports with our team for further investigation. We appreciate your patience as we work to resolve this matter. Thank you all for bringing this up!
