I synchronized my Forerunner 945 to Garmin Connect (using the USB cable) after 15 days without synching. Everything went fine except for just one day (January 15th) where the number of steps was not synched and remained at 0, while the correct amount appeared on the watch.
What can I do to fix this issue on this day? It messed up with my daily steps goal streak. Another sync by Bluetooth did not change anything.
Thanks in advance for your help
