Today I can't get my One to sync to my phone (which means it also won't sync to the insurance company app that gives me credit for a certain number of steps per day, my weight-loss app, etc.) The message I get is:
This version is no longer compatible with your One. Your device may not be able to connect with the app until you update,
Since my app is up-to-date, I'm assuming that Fitbit wants me to update my device. Wish I could figure out how to go back a version or two on the app....but this makes me wonder if they've discontinued all support for the One?
Best Answer@Joenjosie by now I hope it is working, you need to give the Fitbit app permission to access Bluetooth.
Try log out/in.
