We are aware that some iOS users may be regularly logged out of their accounts, and that this has resulted in accounts becoming lost.

While this issue appears to be more widespread than only Supremacy apps, our QA team is in the process of investigating for a solution, in order to prevent these logouts, but in the meantime we would like to recommend that you secure your account with an email address and password, or log in via your AppleID, so that you can quickly regain access to your account should you be logged out in future.

Thank you for your patience as we work on this issue.
