I got this bug on my community. I get a new notification popup when someone likes my posts/replies, but the notification window itself has stayed the same for over 20 hours now.
I've also seen some issues with the ways discussions are being updated. Sometimes when someone posts a comment, the update doesn't appear on the discussion's <li> on the homepage.
I'm using Cloudflare, but I'm not sure how that could be related.
Let me know if I can do anything to debug this. Any help would be very appreciated 🙂
