Is it normal that app spending test mode let you have a negative balance and skip capped webhook?

I'm trying to use the `appSubscriptionCreate` mutation with the `test` set to true, successfully creating a subscription with a $20 app spending cap. Subscribing to theAPP_SUBSCRIPTIONS_APPROACHING_CAPPED_AMOUNT webhook successfully.


When I'm getting to 90% ($18 spent), I'm not receiving any webhook (while receiving for the APP_SUBSCRIPTIONS_UPDATE), and not only that, it lets me get to a negative app spent limit:




Is that normal? It sounds to me like a bug. I would love to hear how I should test this feature with so many expectations on `test` mode.

Hi Idango,


This could be a limitation with using the test mode - I'll look into this further and get back to you asap

Hi, any updates? That is really confusing, as it won't let us test the real scenario by getting the `APP_SUBSCRIPTIONS_APPROACHING_CAPPED_AMOUNT` webhook.
