Yes, you need to specify the environment when you create the sdk key. You can then choose which envs a feature shows up on with a toggle on the feature page, or the feature overview page. https://docs.growthbook.io/app/features#environments

Do you have the Growthbook Devtools chrome extension? That can help debug what is going on: https://chrome.google.com/webstore/detail/growthbook-devtools/opemhndcehfgipokneipaafbglcecjia

In that case, what are your override rules?

You have a default value of off
so I would expect it would be off for everyone

i see. but if i enabled it it will always be true?

correct
in general you probably want to leave it as false but provide override rules for who you want to see the feature

i see. so to change its value i need to change the default value not the enabled environments toggle?

Well the env toggle needs to be on to serve the rule to that environment.

Then the feature will always return the default value unless overwritten by the overwrite rules

my usecase is to enable the feature in an environment. e.g (enable in dev, disabled in prod)

Well one way could be to set the default to true, but disable the prod env var. The other way is to keep default to false, then create an override rule in dev with a 100% rollout percentage.
