Since the launch of TSW4 the R3 button has become very unresponsive when you press it to go to camera view and coming back to the cab view. Have done a ticket and hoping for a quick resolution.
For me this issue doesn't seem as bad as at launch, maybe they've improved it or my memory is bad. Might be specific to certain locos as well. Classic controls also need some love still - L3 to sprint not working despite being listed on the controller mapping as such. Also the sensitivity of the pitch/yaw of that camera is way more than the external cam on immersion for some reason. Don't know how you ship a game with broken controls, especially when they were previously working. Improve your processes, checks and balances. These problems should not be happening or take months to fix.
