Sometimes vendors like Google Play and the App Store make adjustments to app prices in specific markets. This is often due to, for example, exchange rate fluctuations or taxation changes. These adjustments can sometimes be implemented on a fast schedule and without notification.
Gameloft has no power to influence these decisions in any way, as price changes are decided by the vendor only.
