Your software is ***. My top-tier device constantly fails to sync activities, which is its fundamental purpose. It frequently drops Bluetooth sensors, leaving me uncertain before every ride whether it will connect to my power meter and heart rate monitor or successfully transfer data to Garmin Connect.
If the software remains this unreliable, you should at least provide a functional way to export files. A "History > Long Press > Share" feature is a basic requirement you have overlooked. It is clear this device has not been adequately tested by anyone who actually uses it for its intended engineering purpose.
You have one job: ensure the device records and syncs the event. Fix it.
