The last two achievements when you’re playing Multiplayer, Quick Trigger Finger and Multiplayer Champion are not going up with the progress and stopped adding up.
Quick Trigger Finger - 89%
Multiplayer - 80%
It sounds like the achievement progress for these has been stuck for everybody since August 27th, 2020. The same is also the case for me with the “Checking Out Your Options” achievement. Progress for these achievements may have been accidentally ‘locked’ during a recent update. Hopefully they will be fixed soon!
