Sorry for the delay. How often do you log into the Go365 Mobile app? It can take up to 24-48 hours for the steps to transfer after logging in. To avoid missing data you will want to log in at least once per week.
What are the steps missing for each day from 12/31-1/3, I would be happy to take a closer look for you!
Hello! I attached screenshots of both the missing steps and where it skipped on my app in the original post.
