MobileTrack "linked to another Device" message.

[FelixE]

Hello!

Yesterday my phone broke, so I took the sim card out and put it in my other phone but now fitbit doesn’t track anything anymore and when I try to sync it says: Linked to another device

(I don’t own a fitbit watch at the moment)

Hello @FelixE, thanks for joining the Fitbit Community, it's great to have you on board! 

Thanks for bringing this to my attention. If you recently have changed phones and MobileTrack is not syncing or is giving you an error message, my best recommendation would be removing it from your account by tapping the Account button, then select MobileTrack and then "Remove from this device". After that, setting it up once again:

• Tap on Account
• Tap on Set up a new device
• Select MobileTrack and follow the onscreen instructions. 

I hope this can be helpful, give it a try and keep me posted in case you need anything else.
