Hello folks, I want to run an experiment in multiple platforms (ios/android/web). Should I create per-platform feature flag, or just one single flag, then use Feature Rules to manage the experiment on each platform separately?

both are acceptable- typically if the feature is the same, you'd use one flag with targeting rules to adjust the behaviour per environment

yes, the feature is the same. In this case I still need to create 3 experiment copies with the specific targeting and link them to the main feature, right?
