Just awful. No sync. No sleep tracked. No heart rate

I just deleted this piece of garbage and went back to my charge 2. Ridiculous waste of my money and time. Random syncing even after resetting numerous times. Doesn’t track sleep. No hear rate info. Oxygen is 0. Do not waste your money!!!!!!! There is no magic fix for any of these issues. The design and software are faulty. How can you keep selling these. I have NEVER had a Fitbit issue until this version. I want my money back!!!

Try force shutdown of mobile app and restart when that happens.

I have the same problem.  From reading the posts, it seems like MANY people have this problem.  My Charge 4 worked well, and I decided to upgrade.  My charge 5 randomly quits recording my heartbeat.  When that happens, I don't get zone minutes or sleep tracking, etc.  I can correct it by restarting my Charge 5; however, I don't wake up at night to check if my heartbeat is recording properly.  I hope that Fitbit is going have a fix for this.  My Charge 5 doesn't work as well at my Charge 4.

The problem with this is when the heartbeat stops during the night or when you are exercising.  I am having it quit recording my heartbeat about every other day.  There has to be a bug somewhere if so many people are having this problem.  It is frustrating.

Tried it. Also deleted and added the charge 5 many times. Over it. But thank you.
