The toph ranking system isn’t working properly for a long time. In my profile my ranking is 0. I found that bug a long time ago. But I thought it would be fixed in those maintenances done recently. But it is not fixed yet. So I’m reporting it as a bug.
Thank you @Jarif_Rahman for reporting it. I am aware of this issue. I just didn’t have much time to get this resolved. I was out for several weeks and came back to an even more pressing issue, which only got somewhat resolved today. So, I will spend some time on the missing ranking feature soon and get it back working.
