Hello, I am trying to do some advanced targeting via utmSource but I don’t see the option under “targeting”. I’ve confirmed that Growthbook is grabbing utmSource via the console, should I wait for a bit more traffic until I see utmSource as a targeting option? Or should I use “advanced mode”?

Hi @best-wolf-68569 I believe you'll need to add it to your list of Attributes defined in SDK Configuration > Attributes, for it to show up in the GrowthBook UI

Ah I missed that step, perfect it works like a charm. Thank you!
