Hi there, I'm integrating GrowthBook into our Shopify store. I've set up an SDK connection and created a feature of type string with a 50/50 user split. Since we don't use Shopify's login system, I used

guest_id

as a unique identifier instead of

id

. However, the implementation doesn’t seem to be working—I've tested with multiple users, but they all receive the same variation. Looking for insights on what might be causing this issue. Any suggestions?

can you share the code youre using?
