Hi! I understand your steps from FitCloudPro and your watch aren’t fully syncing with Apple Health on your iPhone running iOS 18.5. Let’s work through a few things to get this sorted out.

First, a quick check:
1. Have you granted FitCloudPro full permission to read and write step data in Apple Health? Sometimes, if permissions aren’t fully enabled, the steps won’t sync properly.
2. Is your FitCloudPro app updated to the latest version?
3. Does your iPhone have any battery optimization or background app restrictions that could prevent FitCloudPro from syncing in the background?

If you haven't checked permissions yet, here’s how to verify and set them:
- Open the Health app on your iPhone.
- Tap your profile picture (top right).
- Tap “Apps” under Privacy.
- Select FitCloudPro, and ensure “Steps” is enabled for both read and write.

Next, let’s make sure the sync is working regularly:
- Open the FitCloudPro app and leave it open for a minute or two to initiate the sync.
- Restart both your iPhone and your smartwatch to refresh the connections.
- Double-check Settings > FitCloudPro on your iPhone, and ensure Background App Refresh is enabled.

If the problem persists, try disconnecting and reconnecting the Apple Health integration within FitCloudPro (if the app supports that), or reinstall the FitCloudPro app and reconnect your accounts.

Sometimes, battery optimization settings on iOS can interfere with syncing. To check:
- Go to Settings > Battery, and see if there's any optimization enabled that might restrict FitCloudPro’s background activity.

Have you tried any of these steps so far? That way, I can help you better with next steps if needed.
