Direct answer: Netmarble's September 28 AOS Recommended Update fixes an issue where shader compilation could intermittently repeat when reconnecting to the game on Android devices.
What did the Android update fix?
The official notice lists one confirmed fix: shader compilation could repeat intermittently after reconnecting to the game on AOS devices. This is an Android-specific stability correction; the notice does not claim a general PC or PlayStation fix.
Was there maintenance?
No. The update was scheduled for September 28 at 09:46 UTC and is applied without maintenance. Availability can depend on the platform or device rollout.
What should Android players do?
Fully exit the game, install the recommended update on the Android device, and reconnect before checking the issue. If the update does not appear, refresh the platform or device update flow and try again.
Does this change banners or the Version 2.1 issue list?
No. The notice only confirms the Android shader-compilation fix. It does not announce a new banner, reward, rate, pity rule, or roadmap change. Use the Version 2.1 Known Issues page for the separately tracked issue list.
