Pulse sensor and buttons not working

[ThatKarmaThing]

Hello. My Fitbit app stopped displaying the heart rate trend recently. In the app main page, it shows a heart but clicking on it doesn’t do anything. While examining my Ionic I noticed that my heart rate sensor doesn’t even light up!

I also see that my right side two buttons don’t work. Also my left side button only works to wake the watch, but it doesn’t work as “back” key when I’m in any of the menus!!

Help! I use my Ionic every day and use it to track all my exercises!

@ThatKarmaThing It's nice to see you on the Community. Thanks for the detailed information shared. 

Since you mentioned that your heart rate sensor isn't lighting up, please try the tips mentioned in this article: Why don't I see my heart rate on my Fitbit device? 

You may be able to remove dust or dirt by gently using a toothpick around the button. If this does not improve the button performance, you can try to clear debris using canned air. Hold the tracker at arm's length and spray once to loosen any dirt or dust that may have accumulated around the button. 

Keep me posted. I'll be around if you have any additional questions.
