Polar FlowSync 3 to expire – update to version 4
Previously Windows 10 users with 32-bit version of the operating system could only use the older, unsupported FlowSync 3. They can now update to FlowSync 4. When you download FlowSync 4 from https://flow.polar.com/start for Windows, the installer includes a version for 32-bit Windows 10 users too.
Current users with FlowSync 3 will be offered to download and install the newer version starting today. When you connect your Polar device to sync, FlowSync will provide you with the download link and more information. You will have 90 days to use version 3 and after that it is mandatory to update to version 4.
