Same issue, just got the game free from games with gold . 1st time playing the series btw, and the campaign is awesome.
I don't know why it says there is a solution to this because the proposed solution is garbage. It pretty much states that we are all imbeciles who can't comprehend how to hit start and look at a controller button map.
I first had the issue in "fog of war" mission where you scout ahead of besse the tank . As soon as I picked up a crate weapon, no binoculars....I can only point my arm to tag enemies. It wasn't that bad of an issue until I had to go find spark plugs for besse . You grab a sniper as you climb a tower, get to the top (a prompt even comes up to use the binoculars) to overlook the city, but no binoculars . I can only look down the crappy 1900s era scope and hit rb to tag enemies . Immediately came to Google and this thread popped up .
Glad I'm not a potato who couldn't figure it out, but it sucks it's happening to all of us . I imagine it happens to everyone, but only we took the time to write about it...
Btw I'm playing on an OG Xbox one with a normal controller
