Welcome to the Fitbit Community, @missSerenity23.

Thanks for the details shared in your post, I understand your concern. Usually updates come with new features and bug fixes and if you experience any difficulties, I recommend trying the following:

1. Log out from the Fitbit app.
2. Verify if the Fitbit app is updated to the latest version. For instructions, see this help article.
3. Force quit the Fitbit app.
4. Reboot your phone.
5. Open the Fitbit app and log back in to your account.

I'll be around if you need further help.
