Charge 4 won't sync

[AvrilAdam]

I have had my Charge 4 for a few days and it worked perfectly until this morning and now it won't sync. I sync it to an iPhone X and tried turning Bluetooth on and off and it cannot recognize the Charge 4. Any ideas what to do?

i seem to have solved it by removing device from bluetooth and addding it again.

Welcome to the Forums, @AvrilAdam.

Thanks for troubleshooting this syncing issue. I am glad to hear that this has been resolved by removing and adding the device from your Bluetooth's settings. If there is anything else we can help you with, do not hesitate to post it.

Keep the stepping up! 🙂

Issue with that is you lose all unsynced data, and as this seems to be an ongoing issue it's pretty poor from fitbit it'd put me off buying another.

so, basically..  every single week when my charge 4 gets funky and won't sync I have to remove from bluetooth and reconnect?!  How about FItbit fix it instead so we don't pay $100 for something that infrequently works?!

I have owned my Charge 4 for a week, updated the new firmware and followed the instructions for forgetting my device on my iPhone’s Bluetooth. Have rebooted the app, have removed my watch from my fitbit app,  etc...  My Charge 4 loses its sync sometimes 2-3 times a day, works well for a day then loses it again the next day. My old Charge 2 syncs like a charm every time I run it. Sadly, this device is going back to Costco. Don’t know if I will replace it.

Why do I need to do this (reconnect bluetooth) multiple times per day? The phone app continues to lose connectivity to the Charger 4 all the time.

[Lee0826]

That didn’t work for me.

The Fitbit Charge 4 is junk.  I have had to call and get help multiple times with different issues. I wasn't getting notifications.  Got that resolved for a couple of days.   Now not getting notifications again and now it won't sync. I'm done with Fitbit and will find another tracker.

This doesn't work.  However,  I bought a dongle and can synch to my dashboard thru the app on my windows PC. The problem is the mobile app.

Thanks but didn't help at all. Sometimes it pairs. Sometimes it doesn't.
I've sent it back to the company for replacement; even though it's clearly
the app and not the device, that's the problem. The app is installed and
yet I get the message in the jpg.
