iCloud doesn’t sync

To fix iCloud sync issues on your iPhone 13, ensure iCloud Backup is enabled and connected to Wi-Fi. Try signing out of iCloud, then signing back in. Confirm the apps and data you want to sync are enabled in iCloud settings. If issues persist, contact Apple Support for help.

Do you understand that backing up and syncing are two different functions?

There’s hardly any apps or anything that is supposed to be there. Don’t backup but the settings says it is.

Do you see a "Last successful back up date" if you go to Settings><your account>iCloud>iCloud Backup? If it says that the back up has been recently successful, what makes you think it hasn't been?
