You can no longer see another person’s game history on Waypoint. At least as far as I can tell so far.
It appears all you can see currently is Win/Loss on the main service record.
When I click on the Game History tab on someone else’s service record it instead shows me my recent games?
Not sure why this adjustment was made, but I do think it is kind of silly and I wish they would either fix the error in coding the new UI, or provide us the feature back.
EDIT: NVM I was being an idiot, apparently I forgot how to navigate the site.
