We were just informed by Apple that due to foreign exchange rate changes, prices for apps and in-app purchases will increase in Denmark, Mexico, and all territories that use Euro currency in the next 7 days (it is unclear when exactly it will take effect).
This seems mostly due to the recent strength of the Dollar compared to some other currencies.
From the chart received, as an example the 9.99USD/ 9.99EUR purchase will become 10.99EUR; 89 DKK; 199 MXN. These changes will also be reflected on Android at this stage.
Please understand that these changes are not specific to Arcane Online.
