Traccar SMS Gateway for Android

Hi.
I have installed latest Traccar SMS Gateway for Android from Play.

Trying to sent SMS with cyrilic symbols through https://www.traccar.org/sms/.
Short messages sending properly.
But long (i.e. that must be split in 2 or more real SMS) not sending.

Server answers there is no error on that

{
  "multicast_id": 4197364628949367000,
  "success": 1,
  "failure": 0,
  "canonical_ids": 0,
  "results": [
    {
      "message_id": "0:1622714386193253%21dc6000f9fd7ecd"
    }
  ]
}

Is this limitation of android app or bug?

Could be a limitation of the app. What is this json you have?

this JSON is answer from your server
seems like it sends message: "success": 1

I guess it's firebase response. So, seems like the message is delivered, so I guess it's an app limitation. Feel free to send a pull request if you find a fix.
