The number of profile views of each user is no longer visible. Why has this been removed from MSE?
This is a network wide change announced here. Site moderators are unable to revert changes to the software, so math.se can't get it back unless it comes back for everyone (which seems unlikely).
A bit long method but it would help you to see Last Seen, profile views and member since then you can open this and click on Copy Snippet To Answer and then replace the second line with
const params = "?order=desc&site=Mathematics&filter=!40D72h-7nG92Z1_td";
Then run the snippet and you can see all the three Features.
