Bug: RESTful API /msg/send_msg delayed reception

What happened?

Version: v3.6.0 Problem: When using RESTful API /msg/send_msg, there is a random delay in message reception, ranging from 0 to over 10+ seconds. No delay when using native message sending. Message body:

{ "sendID": "7289801396", "recvID": "8325462764", "groupID": "", "senderNickname": "", "senderFaceURL": "", "senderPlatformID": 1, "content": { "content": "hello!!" }, "contentType": 101, "sessionType": 1, "isOnlineOnly": false, "notOfflinePush": false, "sendTime": 1712462465566, "offlinePushInfo": { "title": "send message", "desc": "", "ex": "", "iOSPushSound": "default", "iOSBadgeCount": true } }

What did you expect to happen?

RESTful API no message reception delay as using native

How can we reproduce it (as minimally and precisely as possible)?
