Not compatible with Polar Devices – Polar Flow Review

I've yet to figure out the purpose of this App, as it does not want to upload any data. App indicates date and time of recent synch, but data is never uploaded. I think this app was designed to keep the software on my M400 up to date and not intended as a record keeping device. Update: Tried Polar Support, they were useless. App not intended to synch with M400; told me to connect M400 to a PC first with a cable!
