Hi GB team, how to define a target group of users with simple rule? I’m looking for a list of user uuids with OR relationship but it seems only AND relationship is offered. Do I have to use mongo query syntax in this case?

There is an operator

is in the list

where you can specify a comma-separated list of ids

oh cool, thanks Jeremy

Yes, that works too

What would be the difference between the two options?

Using a comma-separated list is easier since there's only one rule to deal with. Using separate rules is more flexible since you could have completely different targeting conditions or experiment settings.
