Hi
I'm using Fenix 5, and I have changed my GPS setting from smart to 1 second mode, seems my Garmin connect mobile iOS app always cost about 1-2 minutes to sync 1 activity from Fenix 5 to the app via Bluetooth.
In addition, My datacenter is China Mainland and tried with too many network, included 4G LTE/Wifi, have the same result, so I don't think it's network speed issue.
for the same date center, my colleague using Garmin 235, it can sync 1 activity less than 30 seconds via Android app to China datacenter.
I'm Using iPhone X and iOS tried with 12.x and 13.x, all have the same result.
Thanks
