Inspire HR stopped syncing on all devices

[q00u]

My Inspire HR has been working fine for a while. Today, I noticed that it stopped syncing to my work iPhone. Restarted app, restarted device, restarted phone, still no sync. So I checked with my personal G7 to see if it synced on Android, and it's the same there. Though on Android it additionally says that it last synced "about 2 hours ago", so this _just_ happened.

It's strange, because the phones can still see the _charge_ of the Inspire, so it's still communicating??

But if it's the same on both phones, it appears to be a problem with the device itself. What's the next step, after restarting everything?

Welcome to the Fitbit Community, @q00u.

Thanks for the details shared in your post and for already trying to resolve the issue. If you're using several devices for syncing, the tracker is trying to connect to both and the Bluetooth connection can be interfered. Check if having another device not nearby or turning off Bluetooth on it helps. Regarding syncing with your Android device, make sure your Fitbit app is updated to the latest version as updates come with new features and bug fixes: How do I update the Fitbit app? I also recommend confirming if your Android phone is on the list of supported devices as some of the functions might work intermittently. 

For complete troubleshooting instructions to resolve the syncing issue, see Why won't my Fitbit device sync? 

I'll be around if you need further help.
