Cannot use `v3_singleFetch: true` flag and billing remix function

[BowShopDev]

Hi,
I need to use the flag v3_singleFetch: false to be able to use Response.json in loader and actions.
But i also want to use awaitbilling.request({…}).

But this doesn’t works because billing.request return a redirection but the flag broke this, so i get a 401 error.

Thanks.
