Having issues syncing Fitbit Flex.

[Shopgirl1]

I have reinstalled my app, turned off Bluetooth, I removed device and when I try to reinstall it, finds it but when I get to screen to tap till vibrate its not registering it. I tap it vibrates but says not working.  Help

The usual things to try when you get syncing issues are:

• restart phone
• restart fitbit using this procedure: Help article: How do I restart my tracker?
• restart fitbit a few more times (it doesn't always work)
• "forget" the fitbit in the phone's bluetooth settings
• go through fitbit's troubleshooting guide at: Help article: Why won't my Fitbit device sync?

If none of those ideas work for you then it’s probably best to contact customer support via: contact.fitbit.com

All these guys do is send people links that still dont help people i tried a variety of things by mixing up people forums. I was able to get one flex out of 3 to sync.Be sure to have it charged. Go to phone settings to your fitbit app and force stop clear cache and clear data and unistall the app.Turn on bluetooth and location then restart you phone. During your phone restarting hold the fitbit reset button for 20secs while its on the charger. Reinstall the app log in and setup new device. Be sure that any other devices are far away from your phone and fitbit before setup.And make sure you have fitbit next to your phone and is ready to be tapped once it says it found your fitbit. I dont remember if i tapped fitbit before it said to tap after it was found or when it said to tap. But these steps i combined worked for pne of mine

I did everything that the fitbit "help" line told me to and deleted the flex from my account. And, it did not sync back, it did light up but no vibration and kept stating is not working. The fitbit help line told me that they had instructed to delete all other bluetooth NOT the fitbit flex. This is really frustrating. If anyone else had advise, I would appreciate it.

Could you explain what force clear cache is?
