I've just got a new Garmin Forerunner 235 - activities are saving fine on my watch itself, and the watch syncs fine with the Garmin Connect app on my phone (Huawei P20 Pro), but activities don't seem to appear there. I've seen my watch flash up "transfer complete" a number of times, but yet still nothing appears in GC.
One peculiarity in the Garmin Connect app is under 'Device Settings', Auto Upload is greyed out and I can't seem to turn it on? ("Automatically upload activities to Garmin Connect")
Any ideas:?
