Hopefully you will see this as I have one question. You say the AB settings if you update that can mess with AB settings.I am a moderator over on the Cyanlabs forum also. Very experience in Forscan and can tell you that you have nothing to worry about.
The AB settings carry over fine to the new version and you won't lose anything. Now if you update the calibrations on it that can mess with AB settings.
You have a 2019 so it should not be a 2020+ APIM and reformatting so you get the maps released a few days ago should not be a problem.
I'm not sure what this means but I do have Forscan and did mess with a few things so I just want to know if I need to put them back the way they were or do you just mean i'll have to fix them again to the way they are now after the update? I don't want to update anything until I know so I don't mess anything up.
I'm going from 3.0.2024 (or whatever version it is, i think it ends in 2024), to the newest 3.4 version and updating the maps as well. Let me know though, i'll hold off upgrading til i know about the settings I changed with my Forscan.
