Check timestamps.
Have the same problem. Newest server and client apps installed. Checked the mysql location table and found the server time in the records to be correct (minus 1 hr due to winter time), but the device time lagged 4-5 hours. Records were updated correctly, and the log in the client app showed the right time, however NOT minus 1hr for winter time. So maybe the device (my smartphone) is sending 20:00, while the server is at 19:00 and rejects the data for being in the future. I then turned off the tracking in the device, changed the tracking distance to 0, then back to 50m, restarted tracking and suddenly the server received the right timed data. I know this doesn't make any sense whatsover, but there seems to be some hickup concerning mysql database and/or winter time.
hi.
units are sending the correct location data, i checked the logs, but on the map, the unit is shown on the last location from a previous ride.
