Does stopDownload() work differently on iOS and Android?

[sebqq]

stopDownload doesn't throw "error" promise on iOS while on Android, the promise continues with catch() block. Enclosing the code fragment

fetch = () => {
  // progress callback besides other things, saves the jobId into the state
  Service.download(country, this.progressCallback, this.onDownloadBegin)
    .promise.then((filepath) => {
        const data = this.prepareData(filepath);
        this.setState({data});
    })
    .catch(error => this.catchDownloadError(error));
}

 // this callback is called right after stopDownload() is called on android, but isn't called on iOS!
 catchDownloadError = error => {
    console.log(error);
 }

cancelFetching = () => {
    console.log("Stop download for jobId: ", this.state.jobId); // jobId is 1
    // this statement ends successfuly so stopDownload is called!
    if (this.state.jobId) {
      RNFS.stopDownload(this.state.jobId);
     }
  };

Is this normaI behaviour? Is download cancelled on iOS same as on Android? Do I need to move my catch() block functionality right under RNFS.stopDownload() call for iOS? Does anyone have any suggestions please? Thanks!

Edit

There is a memory leak and when stopDownload is called and after that a go back from the current screen. My progress callback is still receiving data...

It seems like i've solved the issue. At least i have no memory leaks for now :D

For anyone interested, I'm getting jobId from promise instead of progress callback
