Cannot sync replacement fitbit

[AndyBebb]

My wife has bought a new Charge 4 to replace her old Charge 2. I have deleted the old 2 from her account and successfully added the new Charge 4. When I try to sync the app says it has synced successfully , but the steps haven't recorded and the fitbit has a continually scrolling message saying download or update the app. She doesn't possess a smartphone and has always (successfully) used the WIndows 10 app which is installed on a laptop. NOt sure what to do. I couldn't find out how to update the app on the laptop.

I am surprised at that - I have a Charge 4 which works on my Windows PC!

Thanks for getting back to us and for your comments regarding using a Charge 4 with a Windows PC @AndyBebb.

Sep process must be followed with a compatible mobile device. Then you can sync your tracker with the PC. It will work some times but we can't assure that it will be permanent. 

Thank you for your advise and the heads up @Odyssey13.
