Hi
Since 17 June 2014 my Forerunner 405 has stopped syncing to Garmin connect, although I have done a number of runs since then and they are shown in the 405's History > Activities. When I switch to the 'classic' interface and click 'upload' so as to force a manual upload, Garmin Connect finds the 405 but lists the activities on it only up to 17 June. In other words it seems that Garmin Connect is unable to access activities that happened after that date, even though they are recorded on the 405.
Is this a consequence of the introduction of the 'modern' interface?
And what do I need to do to restore normal service?
