As mentioned from our previous post, the issue with the Command Center's upgrade button was detected after the recent maintenance. The patch to fix this issue is now available on Google Play Store.
For iOS, the update is still under review and we are expecting that the update will be available within 24hrs. We will keep you posted once the update has been released on Apple App Store.
We will be posting a notice later once the compensation for this issue has been confirmed.
Our sincerest apology for this experience. We will do our best to provide better service.
Thank you for your understanding.
