doesnt work
On my browser (Brave) it seems to be under the Settings menu at the top right, then Home Settings, then Notifications. I will have to see if that works (turning off comment alerts). I've been getting dozens of alerts a day since I jointed the World vs Vishy, since there are thousands of players and lots of them are posting comments.
Is there a way to turn off email Notification without turning off the move Notification. I am using android.
