In the event that you encounter difficulties saving your activity on FitAnalytica, it's possible that the number of steps tracked during the activity may not meet the minimum threshold required for it to be saved. In such cases, the app may not recognize the activity as a legitimate exercise session and may not save it in your activity history. If you think this is the case, try tracking your activity for a longer period of time or increasing your pace to ensure that the app accurately captures your movements and records the activity data.
