Some Android devices might have the same device identification, and those devices will fail to enroll in MDC.
  • Installing ERA Agent on macOS Sierra (10.12) requires root privileges.
  • MDM can stop working after a mobile device's static object is removed (for example, if a task or policy is removed from the device).

  • When performing an upgrade of previous versions of ESET Remote Administrator to ESMC V7 it might happen, that it is not possible to login to the web console for a longer period of time.
  • Using emojis or other 4-byte characters in certificates & object names will cause database errors and server crashes in some cases.
