I guess this is a result of the recent data center migration that's happened to Garmin users in China. Now my Garmin account registered in the US is blocked from receiving updates from all my contacts in China, and vice versa for my friends' accounts registered in China. I think going forward I will have to maintain two separate accounts (US/CN) to keep connected with friends everywhere.
Now the question is, is there any easy way to upload all my activities to both accounts (other than exporting.fit files from one account and then importing them into another)?
Also, would it be possible to login into GCM using two different accounts on two different mobile devices (e.g., US account on iPhone and CN account on iPad), then have my Garmin device (a Fenix 3) syncing with both, without losing any data on either account? Basically what I need here is sorta a mirrored account.
