Riddler Forensic Scanner bug?

[Mr. Hanky]

Ok, before the wrath of the internet descends upon me... Yes, I have used the search function to try and find a solution, and it has yielded no results other than a bunch of topics that bluntly state that there are tons of other threads about this that offer the workarounds and you should just used the search function already!
I am trying to do the riddler batmobile forensic scanner trophies. None of them work. Most of the time, no or only one or two question marks appear. Every now and then I can get a whole bunch to appear but they never go all the way to the end. I have tried looking up the path you're supposed to follow and where you're supposedly needing to shoot, but it has yielded no results. Please someone, if you know how I'm supposed to solve this issue, please tell me or at least refer me to where I need to go to find out. Thanks!

I have, which I thought was implied in my original post.

The question marks are quite fiddly. I usually get bihind the last one that's revealed and wait for the next scanner pulse. Try pointing the camera in various directions to try and trigger the marks appearing.

You seem to need to be "standing" before the last visible marker, and looking in the direction of the next (invisible) marker for it to appear. Even so a few riddles will take a few attempts to work, because the markers are fiddly bastards. Especially when changing height/level, but that may be because while you get in the new position the last marker or two have already disappeared, and you can't skip any.

Keep spamming the sonar scanner pulses in every direction. That's how i did mine, but some of the are really annoying.
