Consumable items can't be purchased twice

I am trying to set up an in-app purchase for a virtual currency for my app. The purchase works fine the first time, but then the second time, after hitting the “buy” button in Apple’s popup, I get a message saying:
“You’ve already purchased this In-App Purchase but it hasn’t been downloaded.
[Environment: Sandbox]”
I set this item up in iTunes connect as a consumable good, so shouldn’t that error not come up? If it’s a consumable, you can buy an item twice (or so I think).
What does anyone know about this? Is there anyone who’s successfully been able to get a consumable in-app purchase working?

Are you calling store.finishTransaction( transaction ) after the purchase? It sounds like Apple isn’t being notified that the purchase and download have gone thru. [import]uid: 58885 topic_id: 21557 reply_id: 85434[/import]

As far as I know, the finishTransaction call works fine. (My print statement the line afterward fires and there are no errors) Is there any other problem that would cause this? [import]uid: 38000 topic_id: 21557 reply_id: 85707[/import]

Did you ever resolve this? I am experiencing the same thing. [import]uid: 51494 topic_id: 21557 reply_id: 88723[/import]

No, I have not yet resolved this. (If anyone else can help, please do!)
It seemed to work sometimes, but others it didn’t, so I just put another IAP with a higher amount of virtual currency in my app, and then let users choose. I have yet to have any users contact me about this problem, so I assume that it has not yet been noticed. (although I would love to get it fixed!)
