Welcome to the Forums @DeSwish! Is this happening with recent exercises or did it delete the data from past activities as well? You can check out if your account is connect to third party integrations in this site. Have you tried logging out and back in from the Fitbit app? Also, if you could share a screenshot it would great, to better understand this matter.
Looking forward to your new comments.
