Purchase item problem - more devices with same Google acount

[HonzaR]

Hi,

one purchased item should be purchased on more devices with same Google account, right? "getPurchases(PurchaseType.PRODUCT, null)" returns different results on 2 devices. On first device I get this item as purchased after I bought it here, but on second device it seems not purchased, even after app close and reopen it seems not purchased. Only after app data clear I got it finally purchased here too. Is is library bug? Thanks for help.
