Cell phone updated, Fitbit confused

[BCfree]

My android phone installed an update. Fitbit says it cannot sync, wrong pass key. Never had pass key. I've tried for 2days. I've never had any problems before.  Thanks for your help and timr  time!

@BCfree Hi and Welcome - I will try and give a suggestion or 2 but would you provide your device type and phone type to pin down the error,

in the mean time was your device already set up and working before the update - and was it already paired to your phone?

it may just need turn off blue tooth - then go into settings>app>fitbit>storage>clear cache and then restart phone - then go back to Bluetooth and turn back on

if you are trying to set up a device you will need to do this via phone or PC and not over Bluetooth - I can provide further information on this once I know the device and phone type

alternatively you can contact  Customer Support for a more immediate response
