    Console: We changed how to check the number of your bot's friends

    We moved information related to the number of your bot's friends from the LINE Developers console to the official account management tools. We removed this information from the "Number of friends" tab on the "Statistics" tab of the Messaging API channels.

    To view the number of your bot's friends, click the Account Manager Official Site button in the "Number of friends" tab. LINE Official Account Manager or LINE@ Manager will open according to your account plan.

    To use the official account management tools, you need separate access permission. If you cannot access these tools, please contact the tool administrators of your organization.

    We will remove the "Number of friends" tab from the LINE Developers console on March 26, 2019.
