I've seen this topic posted in the help section by others but has gone unanswered by Bungie so far. Wanted to get this topic in feedback section to hopefully be addressed.
The crucible doubles grimoire is currently not tracking wins. I ran it yesterday for a couple hours with a friend, and checked the card after and win stats are still at 0 even though we had many wins in that timeframe.
Please take a look and update. For other guardians in the community who have noticed/confirmed this issue and are stopping by here, please help by confirming and bumping thread for Bungie Devs. Thx!
