Replacement Ionic heart rate not working

[KG50]

First Ionic went wrong after 18 months, was sent a replacement which took 2 weeks to arrive only to find out that the heart rate monitor isn’t working and the green LED lights aren’t flashing so exercise, calories, sleep not correctly recording. Emailed support but not heard anything back, seriously looking at ditching this watch and getting an Apple. What a waste of money!

Hello @KG50 thanks for bringing this to my attention, welcome to our Community Forums. 

I appreciate all the details that were shared in your post, I totally understand how frustrating this matter can be for you even more when it's a replacement device you recently received. If you haven't already done so, I recommend you to restart your Ionic following the next steps:

1. Press and hold the back and bottom buttons until you see the Fitbit logo on the screen. 
2. Let go of the buttons.
3. If you still have issues with your device, turn it off and turn it back on. For more information, see How do I turn off my Fitbit device? 

Also, please note that by default your device heart rate setting should be in "Auto," which means the heart rate sensors are on when the tracker is on your wrist. To verify that the heart rate sensors are on, scroll to Settings and check such information. 

Please try the steps above in the meantime our Customer Support team get in touch with you. You can also contact them via chat or a phone call. For more information please check: Get Support.

Looking forward to your reply. Let me know if you have any additional questions.
