I know that my 16 and Mac are syncing properly with iCloud.com.
This is hard without knowing what you've tried, so I, too, am frustrated. Have you
- re-started your Mac?
- Forced restarted your iPhone?
- re-started your Mac in Safe Mode?
- Checked to see if the Photos Library you are using is your System Library?
- Looked to see what's at iCloud.com?
- Checked the "syncing with iCloud" indicator on your iPhone?
- Checked the "syncing with iCloud" indicator on your Mac?
- If you're using an external drive for your Library, checked its formatting?
- tried a different user on your Mac?
- determined that you have more than 10% free storage on your Mac?
- determined that you have more than 10% free storage on your iPhone?
- determined that you have more than 10% free storage on your iCloud account?
Other things I think of depend on what you've checked so far-- and what results you got from each trial, so I'll stop.
