I want to be able to run AB tests that consistently drop a user into a specific (randomized) experiment experience - no matter which browser they sign in on. The experience is post sign in - so essentially I want to randomly assign user ids to test and control - as opposed to visitor ids. Is this possible? I cannot find out how to do this in the documentation. Can someone point me in the right direction - I may be looking for the wrong thing!
Just to be clear (double and triple check!) - as long as I am targeting a page post sign in page - Adobe Target "magic" will make sure that a user dropped into a experience A will always see experience A no matter what browser they use? How does it do this?
