Hi there, @Cbcos. Sorry about the problems but happy you found us here in the forums. Like you, I switch between my Flex 2 and another fitbit device. Here is how I keep from loosing steps when switching between devices. It’s a little extra work, but it works 100% of the time for me.
- When I am ready to switch from the Flex 2 to my Alta HR, I pull out my phone, open the Fitbit app and manually sync the Flex 2.
- Only then do I walk to the room where my Alate HR is, open the Fitbit app and sync the app again.
- Check to make sure the Alta HR shows the correct amount of steps, then put the Flex 2 away, put the Alta HR on my wrist and go about my day.
- When switching back, always manually sync the current device before coming in range of the next device.
The thing to remember is that All Day Sync does not mean constant sync. There can be a gap and it sounds like you are getting caught in it. Tap here for more details. In my experience, when switching devices, it is best to take control of the syncing. Please let me know if this works for you.
