We are planning to discontinue support for Apple iOS 11 and Android OS 5.0 in the near future. If your device is able to support a newer OS version, we would encourage you to update to a newer version as soon as you can.
We'd love to keep supporting older devices, but some of the 3rd-party libraries we depend on have decided to discontinue the support for these OS versions.
We will notify players via in-game message once we have more details about the timeline.
We realise that this is a disappointment for the users affected, and we sincerely apologise for the inconvenience caused.
NOTE: This announcement previously incorrectly stated that we would discontinue support for Android OS 5.1. This error has been amended.
