Since 2 days ago, i am unable to manually or automatically upload any activites from my 510 as well as my 220. Strava uploads are working fine with the devices. Few friends having similar issues with their 910xt.
any idea whats going on?
I've being having the same issue with Garmin 810 also since last Thursday evening 6th February 2014...
I'm also in Perth, Western Australia - Thanks for the Time Zone change suggestions. I shifted my Garmin Connect Profile Time Zone from Western Australia to China zone and it now picked up all activities that I previously hadn't been able to load.
Same for me - changed to GMT +8 China and all activities that I tried previously to upload where already there...... Maybe Garmin should outsource support to their users......
