Network connectivity may have been disrupted while the row was in progress, specifically at the end of the workout. If Hydrow can't communicate with our servers at the end, Nothing will be saved.
Improper region or timezone settings on Hydrow can also cause this problem, though they would do so on every workout
Your workout statistics for any given Row are recorded and reported only when you exit back to the menu. This could either be at the natural end of a row, or if you choose to end it early.
This means that If your network either disconnects or is disrupted at the time when a Row exits, no information gets uploaded to the server for purposes of leaderboards, team racing, etc.
Our systems automatically recheck and verify workout data on occasion, so you may see it show up after a week or two if it was lost in this way.
What steps to take:
We find that the most common cause of this symptom is due to momentary network cut-outs, either due to weak Wi-Fi, Interference, or other connectivity issues. If this happened to you just once or twice, it is likely not cause for concern. If you find that this happens frequently over weeks of rowing, you may want to try Troubleshooting Wi-Fi Connectivity in your setup.
If you managed to either not select a time zone, or set Hydrow's timezone to "automatic" then that may also be the cause of this error. In this case it may be advisable to contact Hydrow support for assistance in performing a factory reset to clear these time zone settings.
