This question already has an answer here:
In the new topbar's Achievements dropdown (the graph icon), badges that you earn are listed. However, when you click the badge notification, it doesn't take you to the badge you earned. For example:
Here are 2 recent Achievements for me. The top is a badge, the bottom is earned reputation from an upvote. Both links go to the post. The badge earning notification says 'See your profile', but nothing in that notification links to my profile.
In the old topbar, there was a section for recently-earned badges. When you clicked the badges there, it would take you to a page that showed you the badge, its description, and a link to the post that earned you the badge. Can we get that behavior back?
It's more useful to understand what the badge is and how you earned it. The link to the post doesn't tell you anything about what's special about that post that makes it badge-worthy.
