I was using react native iap version 4.4.3 and currently i have upgrade my react native version 0.66 and react native iap version 7.53.
consumeAllItemsAndroid method was worked for purchase same product again in the android but now this method has been deprecated and alternate method is flushFailedPurchasesCachedAsPendingAndroid which is not Consume all items so we are able to buy same product again.
As per the iap change log 7.2.0
flushFailedPurchasesCachedAsPendingAndroid:- Consume all 'ghost' purchases (that is, pending payment that already failed but is still marked as pending in Play Store cache). Android only. for more information please check this link
So how would I able to purchase same product again in android?
