Sendbird admin message disappearing after sometime

Hi,

i am using sendbird chat.js . i was able to post admin message successfully .but after some time the admin message disappeared. is this the expected behavior.

following is the request body
{

 "message_type": "ADMM",

 "mention_type":"channel",

    "message": "admin message",

    "custom_type": "",

    "is_silent": true,

    "created_at":1606885395453,

    "is_removed":false

}

Thanks,

Hi @Rajeev_Bhaskaran did all admin messages you created disappear and never came back? Please let us know your application id and sdk version.
