Thank you for using Vket Cloud. With the Vket Cloud SDK update on October 29, 2025, the RTC system has been switched from the legacy [Former SkyWay] to its successor, the [New SkyWay.] Please note that after April 30, 2026, when the former version of SkyWay service ends, the status of your world will depend on the SDK version in use: ・Worlds using SDK v13 or later Will be automatically updated to the new RTC system. ・Worlds using SDK v12 or earlier Will not be updated automatically, and multiplayer will no longer be available. If you are currently using SDK v12 or earlier, please update to SDK v13 or later as soon as possible. Read here for update instructions :
