Having an issue with my Fenix 5x since last week. Activities record fine on the watch. They will not sync via Bluetooth to Connect Mobile (Though everything else -- steps, heart rate, etc -- does, and I get notifications on my watch from my phone, so I know the connection is fine.)
They also will not sync via WiFi. For some reason it has never "auto synced" since I got the watch, but I have manually selected "connect to WiFi," and while it says it is uploading data, no activities show.
They will, however, sync if I connect the watch via USB to my computer and use Garmin Express to pull the activities off. This is kind of a pain.
It's super weird. I've tried updating the watch software from 2.90 to the Beta 3.22 to see if that would remedy it, but it did not. I've tried removing all of the activities from the folder on the watch and then trying again, but to no avail. I can't see any logs in any of the folders on the device, and I don't see any error messages when trying to upload via bluetooth or WiFi. The only thing I haven't tried yet is a factory reset, which I'd like to avoid if possible unless that's the only option.
Anyone have any ideas?
