Step History Disappeared

[RammaAus]

Last night my entire step history (many years) in the Samsung Health App has disappeared. Other history (HR, Sleep etc.) is still showing and fine.

Any ideas how to recover?

I'm on an S21 Ultra.

The only possible thing I noticed is I may have hit exactly 10,000 steps right on midnight. Not sure how that would affect it.

Now you need to backup🤣 Settings, search for backup. Option is to use either Samsung or your Google account if you have one, I prefer Google. I don't quite trust backups not to overwrite earlier backups so see if a backup as saveas available. If you have an sd card you can save to that as a secondary backup.
