I just finished downloading Halo 5 Guardians and I am seeing a Zoom in problem to where you scope in with any gun before you shoot sometimes it will cancel out your zoom randomly while you are still holding the zoom trigger or say Left Trigger. If anyone else is experiencing this issue as well please follow up and post your comment about your side of problems with the zoom feature so 343 can fix this issue if this is an issue.
I might be just tired and seeing it wrong lol
