Web Billing Error: RevenueCat using Production Key (pk_live) for Stripe Sandbox Account

Hi RevenueCat Team / Community,

I am encountering a persistent account_invalid error while testing RevenueCat Web Billing with Stripe. It appears that RevenueCat is attempting to use a Production API Key to access a Stripe Sandbox Account, which results in the following error:

JSON

{
  "error": {
    "code": "account_invalid",
    "message": "The provided key 'pk_live_******************' does not have access to account 'acct_1SZWXNDHtgf1OqUX'...",
    "type": "invalid_request_error"
  }
}

What I have already tried:

1. Stripe Side: Revoked/Deleted the RevenueCat app from my Stripe Production dashboard and re-connected it only to the Test Mode environment.

2. RevenueCat Side: Deleted the main Stripe account under Account Settings -> Project -> Stripe.

3. App Configuration: Verified that the "Web Billing" app provider in the RevenueCat dashboard is correctly linked to the Stripe Sandbox account.

4. Product IDs: Confirmed that all Product Identifiers match correctly between Stripe and RevenueCat.

Observation: Even though the configuration points to Sandbox, the error message clearly shows a pk_live key being used. It seems as though RevenueCat has cached the production credentials or is defaulting to the live environment despite the sandbox mapping.

My Environment:

• Framework: Vue 

• Implementation: RevenueCat Web purchase links

Is there a specific way to force the backend to clear cached Stripe credentials, or is there a configuration step I might have missed to ensure only pk_test keys are used for sandbox apps?

Any insights would be greatly appreciated. Thanks!
