Hello and welcome to the Fitbit Community @Mrs_t_25
I understand you have a new iPhone and your having difficulty pairing with your new iPhone XR. If your still paired with your iPhone 8 please unpair it as it can cause issues. If that does not resolve your issue please try these troubleshooting steps. Hopefully they can get you up and running again.
First let’s try restarting your Fitbit Tracker. Heres how:

If your still experiencing issues try turning your Bluetooth off then back on again.
If restarting and toggling the Bluetooth doesn’t help I would suggest force shut the App and restart. Here’s how:
Turn off your Bluetooth
log out of the Fitbit App
completely shut down your device, wait 1-2 mins then restart your device
once your device fully loads enable your Bluetooth again
now log back into your Fitbit App as you normally would with your email address and password
now sync your device
If your still experiencing an issue try this: please go to the Bluetooth settings on your phone and remove the tracker. In the list of Bluetooth devices you'll see the Fitbit Tracker and next to it, this symbol "!". Hit the symbol and it will take you to the next step, once you're there select the option that says "Forget this device" or "Unpair". Once you've made sure about that, go back to the Fitbit app,, tap your profile picture then scroll down and select "Set up a Device". This should start the setup process for your device. Just follow the instructions as they come.
If the issue is not solved after the above steps, please take a look at the help articles: Why can't I set up my Fitbit device? or Why won't my Fitbit device sync?
😃 Please let me know if this resolves your issue. If it does indeed resolve your issue could you please tap the “choose as best answer” box just under my post? Doing so really helps other individuals who come to this community looking for answers to questions similar to your own. I’d really appreciate it!
