If Rockerbox loses connection to your ad account you will receive an email and a notification asking you to re-authenticate the account in Rockerbox.
Until the account is re-connected, spend for the platform will not be reported in Rockerbox.
Re-authentication may be required if you change your password in the ad platform, or if the user whose account is connected no longer has access to the ad platform.
The user who authenticates the account should have full admin access to the ad platform.
