An incident occurred in which the same device token was sent from different IDFVs. To investigate the cause, please let me know the informations below. ・What are the conditions under which the IDFV changes? ・When an IDFV changes due to uninstallation, etc., does the device token always change? ・Is there a chance that a device token that has been used in the past in another terminal will be used in another IDFV terminal?
