Shopify Billing API won't leave test mode

[carltoni]

Hi,

I'm at a loss here, my app has been approved, yet won't exit out of the test mode for subscription creation.

I have tried test:null, test:false, omitting it completely, ensuring the ENV is set to production, everything.

Every time I go to install the app, even from the public app store, I get "You will not be billed for this test charge."

Anyone have any ideas?
Thanks
