Strava is having trouble correctly uploading swimming activities from Polar Vantage M

[Jussi]

Hello, when I upload my swimming activity from Polar Flow to Strava I always encounter the following issue. The swimming distance on Strava is consistently one meter shorter and Strava always includes the rest time in the total activity time. This results in inaccurate time and distance data. Is there a solution to this?

Polar has given me an answer to my question: "Hi there, rest time information is based on the information we record with the built-in accelerometers / motion sensors in our devices. Unfortunately, at this time, it is not possible to include the motion sensor information to the file sent to Strava, and thus Strava interprets the rest times as swimming time."

Hello @Jussi 

Thanks for posting about this. We are aware of this issue and have reported it to Polar for further investigation. 

At this time they have stated that they will be working on a fix for newer Polar devices, so I would recommend that you reach out to Polar support to see if your device qualifies. https://support.polar.com/us-en

We appreciate your patience and apologize for the inconvenience.

I have the same problem. If I connect Polar to Strava, it takes for example 1998m instead of 2000m swim distance even if i correctly gave the length of the swimming pool. In the polar app the distance is measured correctly so its a problem when transferring the data.
