Hey @Paulinel glad to hear from you! I think I might need a little clarification on the issue here. When you mentioned it synced in two parts. Do you mean you have two different sleep records or that the Alta only synced twice? Also remember that if during your sleep you have a long period with too much activity it will be counted as a wake up and interrupt the sleep log. Lastly are the missing 40 minutes at the beginning or at the end of your sleep time? If it is at the beginning of your sleep time remember that the record starts after an hour the device not tracking activity.
Hope to read you soon! Tchiao!
