Is it possible to have an assignment condition that is not verified for users that are already assigned to the experiment?
We have an experiment that depends on the user not having a user id. The thing is that once they log in, they are unassigned from the experiment. I would like to be able to change our condition so that those who have a user id but were assigned before (traffic is split based on another id), keep their assignment

often event trackers will have an anonymous id or similar that will not change on login
if you use that as your hashing attribute it will work as you want

are you not wanting to expose existing logged in users?
I have a feeling you can get what you want by just targeting to sessionId (assuming your okay with that level of stickiness)

Okay, thank you. I will look into it

Yes, then I think that will work
With the rule you have, when the user logs in, they won’t trigger the trackingCallback - but it will have fired previously when userId is null, so it will still count. Btw, you could also create a boolean attribute called isLoggedIn and target to that to make it easier if you intend on doing more of these.

Just to make sure I understood, you suggest just splitting traffic using the sessionId, right? Wouldn't this consider the existing logged in users? On the tracking-side, I could use the previously fired event, but I would not be able to get this in the app without using some sort of storage, right?

there are a few ways to handle this situation - one would be to target to session id or another anon id, and then filter out the logged in users on the reporting side. Another would be to use the logged in/out state as an attribute, and target to all anon ids but exclude ‘logged in’ users
