We’re currently tracking a sudden drop in sync notifications from Google Health. Normally, Google Health sends these notifications each time your fitness tracker syncs new data, letting StepSmash know there’s fresh activity available to import.
Because Google Health isn’t currently sending these notifications, StepSmash won’t automatically detect and sync new activity. Until this is resolved, you can manually sync your account by going to Settings > Fitness Accounts and tapping Sync Now on your Google Health account.
