Update: Capcom has denied rumours of a rift with Apple. In a statement sent to PocketGamer, the publisher claimed that "We are in frequent communication with Apple, and at no point have they expressed any displeasure to any representatives of Capcom Mobile in regards to our handling of in-app purchases within Smurfs' Village."
The firm also said it had not heard of the aforementioned plans to tweak the login process, but "we welcome any update that would minimise inadvertent in-app purchases and improve customers' experience with our products."
Apple has allegedly issued a warning to Capcom regarding its free-to-play iOS game Smurfs' Village, which thanks to microtransactions has been a recent mainstay on the App Store's highest-grossing charts.
Recent media reports have held that some parents are concerned by the ease with which their children can buy virtual goods in the game, which is age-rated as 4+. One eight year old was found to have spent $1400 on in-game items and currency.
Some items sell for as much as $60, but can be bought automatically if one of the Apple device's users had logged into their iTunes account within the last fifteen minutes.
PocketGamer cites a "well-placed source" as claiming that Apple has been in touch with Capcom about the perceived problem, and that some refunds have been issued.
Additionally, the as-yet unconfirmed report suggests that Apple may soon require more frequent logins from users in order to limit repeat purchases.
Capcom's game does offer disclaimers warning users that real money is involved, plus the option for in-app purchases can be deactivated in iOS devices' settings.
