Purchase status updates during purchase process

I noticed that it takes a few seconds to load the purchase screen in iOS after calling `Purchases.purchasePackage` in the React Native package.

It also takes several seconds after the user completes the purchase before the receipt is acknowledged and this method returns a result.

Is there any mechanism to know which part of the process you’re in?  I’d like to be able to inform the user at first, “Loading . . .” but then change it to “Confirming purchase . . ..”

Thanks!!!
