Fitbit Versa. The fitbit app doesn't have the sleep tracking function any more. Why is this?

Welcome to the Fitbit Community, @Marjismith.

Thanks for the details shared in your post. I understand your concern and recommend confirming if your watch is paired to your Fitbit account:

1. Tap the Today tab, and tap your profile picture.
2. If you don't see any device paired, tap Set Up a Device.
3. Choose your device and follow the on-screen instructions to continue.

You can also try the steps to add tiles on your Fitbit app dashboard at How do I add, remove, or rearrange tiles on my Fitbit app dashboard?

Additionally, I recommend checking if your Fitbit app is updated to the latest version as updates come with new features and bug fixes: How do I update the Fitbit app?

By the way, I've moved your post to Android App board so we can keep our forums organized.

Hope this helps!
