What this means
Flipnote Studio requested an unsupported sign-in feature.
Flipnote Studio asked the sign-in service for a feature that the service does not support. The original Flipnote Studio client should not normally need unsupported NAS features; if it appears on RexiMemo, report the code and app/console version.
What to try
- Retry once after restarting Flipnote Studio. A one-off failure can be temporary.
- If the DSi connection test succeeds, avoid changing unrelated Wi-Fi settings.
- If the same code keeps returning, contact RexiMemo support and include the complete code and the action that triggered it.
