NFC Tag Writing Issue

Hi guys l need your assistance please. I have NFC reading and writing on my app. The reading is fine it’s the writing part that is an issue. If l start my app and proceed to go to writing to tags and the tag writing works but if l navigate to the previous page and go back to the writing page the tag writing when you try to write to tag it keep on giving a success message but it’s not writing to the tag. I have to restart the app for the tag writing to function again.

Is there something that l am not switching of from the tag or is there something hanging when l navigate to the page.

Any assistance or pointing me in the right direction will be much appreciated.

Writing Function Code below
writeTag(tagData) {
this.writeDate = moment().format(‘DD-MM-YYYY HH:mm:ss’);
this.tag = tagData?.item;
console.log(this.tag);
this.platform.ready().then(() => {
this.writingTag = true;
this.listener = this.nfc.addNdefListener((res: any) => {
console.log('Listener is Active: ’ + res);
}, (error) => {
this.presentToast(error);
}).subscribe(() => {
const referenceNumber = this.ndef.textRecord(this.tag?.reference_number);
const date = this.ndef.textRecord(this.writeDate);

    this.nfc.write([referenceNumber, date]).then(success => {
      alert(JSON.stringify(success));
      if (success === 'OK') {
        this.listener.unsubscribe();
        this.presentToast('Successfully written to RFID Tag!');
      } else {
        this.presentToast('Could not write to tag sucessfully!');
      }
    }).catch(error => {
        if (error === null) {
          this.presentToast('Tag could not be written!');
        }
        if (error === 'Only one Tag Technology can be connected at a time.') {
          this.presentToast('Failed to write to tag sucessfully, please try again!');
        }
      });
  }, err => {
    this.presentToast(JSON.stringify(err));
  });
});

}
