Swimming Activity reboot

The watch keeps restarting and discarging the swimming Activity after ~40 min. I do a lot swim Training in the Winter and do Not track Distance. WE are doing a lot af technical Training. Therefore i am using the "Special Mode" within swimming. In this Mode the watch restarts after around 40 minutes. Anybody else? 

  • Yes my F265 resets when i end the 1st 500m drill. This has been happening since the latest update a few weeks ago. I contacted Garmin when started happening and they sent me a reburbished F265 but it is still happening with the replacement. I contacted Garmin yesterday and they said they will investigate it but they never e-mailed me a reference number
