I've accidentally saved over an experience in Target.
I've corrected this by finding the old code in my own records I keep and updating the experiment again but have a nagging feeling it isn't identical to the original code.
Is there any way to check?
No. Unfortunately there is no way to roll back to a previous version/save-point although that would make an awesome feature. I've submitted this idea for you here. Please vote it up: Ability to roll-back to a previous save for previous experience changes
If this helps you don't forget to like, mark as helpful & mark as answer as that helps me Hope you have a wonderful day.
