If you're seeing that message, you just need to offload the activity data stored on the Bio 2.
Please open the Striiv app and sync the tracker.

I have hardly used my striv and when I charged it I receive a notification repeatedly saying storage is full and to sync with app. Not sure how storage could possibly be full. I have synced a number of times. I have removed app and re-installed. I have factory reset tracker. The screen keeps flashing up Alex hr. What do you advise please?
