Not getting noticiations to my LG G6

[SunsetRunner]

My ionic was working perfectly with my old phone ( Samsung edge 7 ) when it comes to notification.

Now I have a new phone ( LG G6 ).. and I hardly receive any notification on my ionic.. I cannot even get the notification test when I send it.

Even though, it's always connected through Bluetooth and I have all the settings done correctly.

So, Why is this happening?

Welcome to the Fitbit Community @SunsetRunner! The reason why you are not getting notifications on your LG G6, is due to this mobile phone is not yet a compatible device with the Fitbit app. This means that our Android team has not yet tested it for compatibility and added it to the list what means that we don't have a estimated date on when it will be added. If the device supports BLE (AKA Bluetooth 4.0), maybe that is the reason why you were able to connect it. However, we don't guarantee all the functions will work as they should due to the incompatibility, as you're having now with the notifications. 

Knowing that, I'd try the following in case these steps work with your LG G6:

• Your phone was too far away. It must be within 30 feet of your Fitbit device to transmit the notification.
  For texts, you have the conversation open on your phone. Your Fitbit device shows new texts you haven't already read.
  You changed a related setting on your phone, such as turning on Do Not Disturb, Quiet hours, or Driving mode. 
• You're using another Bluetooth product. If you have Bluetooth products like speakers, headsets, or car stereos paired to your phone along with your Fitbit device, you may have trouble using more than one at the same time. 
• The connection between your phone and Fitbit device is unstable. Bluetooth signals are susceptible to disconnecting or dropping occasionally. Since  you have an Android phone, check the following:
  • Make sure Enable Notification Widget is on. You can find this with the other notification settings in the Fitbit app.
  • Make sure Always Connected is on. This improves your Bluetooth connection but also drains your Fitbit device's battery more quickly. Turn it off and on as you prefer.
• The app that should send the notification can't do so. 
• Your device was syncing. Syncing can sometimes prevent or delay a notification. 
• You just updated the Fitbit app. Restart your phone and try setting up notifications again.

If you've reviewed the list above and can't get notifications to work, force quit the Fitbit app and reopen it to sync your Fitbit device.

Notifications should work as expected after your device syncs. If they don't, continue with the following steps:

1. From the Fitbit app dashboard, tap the Account icon >  your device image.
2. Tap Notifications.
3. Turn off all notifications
4. Turn off Bluetooth on your phone.
5. Restart your phone.
6. Restart your Ionic.
7. Open the Fitbit app and turn notifications back on.
8. Sync your phone.

Hope this really helps!
