I recently got my old Vivosmart HR+ back on my wrist after 2 or 3 years of not using it. I can see daily steps but nothing is updated into my app calendar. So the next day all daily steps disappear and a new day starts. The same with all the other metrics, my calendar is empty.
Its the latest software version because I had to install it again on my latest phone. My phone is compatible I already checked that.
