Corrupted activity uploads and losing GPS data
1. I'll complete a run and start the sync from the app using the bluetooth connection from my phone to the watch.
2. The progress bar goes about 40-50% of the way through and then will display a connection/upload error message in the app.
3. I try again a couple times but it keeps failing.
This has only happened twice in 300+ runs over the past two years so it's a very rare situation, but both times I completely lost the GPS data for my runs. The activity does not appear in https://mysports.tomtom.com/app/activities/ nor are there any files under the File Sharing folder for the Sports app when I connect my phone to iTunes. It's as if the GPS data is just completely vanished, could be a bug or timing issue of some sort when the phone and watch temporarily lose bluetooth connection or something. This has only happened while uploading using my phone and the bluetooth connection with the watch. One thing that I feel could safeguard against this in a future update is if TomTom stored at least the previous activity GPS data on the watch somehow even after it has been uploaded to the MySports database. That way in some unlikely event that I need to recover data from a failed upload I have at least the previous GPS data still there. I thought this was already done as I could view the run history, but through research I discovered the run history just shows 6 data points and doesn't save the GPS data for any previous activity after an upload attempt to MySports.
Not sure what the storage limitations are, but even my longest runs (20 milers) are in the 600-700kb range in terms of .ttbin data size. If this could somehow be archived for at least one activity and remain in a recoverable state on the watch that would be amazing to see in a future update. Otherwise I am going to stick to uploading to MySports strictly through my PC from now on!
