I am trying to use invoices api for my iOS app to verify payments.
It’s unclear to me if the invoices api is in beta or not due to seemingly conflicting information.
In the RevenueCat Documentation “RevenueCat Billing … currently in beta”:

In the API V2 Documentation

In the above screenshot we don’t see any warning for beta use. Is this api get request reliable for production use to verify how many invoices have been processed by a given customer? If yes, how long until after the payment is processed do the invoices updates (minutes/hours/days?). Also what is the lifetime of invoices. Do they never expire?
Thanks
