Hi there! I'm sorry to hear that you’re having trouble adding your flight to the Oman Air mobile app. I can definitely help you with that.

First, let's clarify a couple of things:

1. Are you sure you're entering the correct reference number? The booking reference is usually a six-character alphanumeric code.
2. What happens when you try to enter your information? Are you seeing any error messages, or does it simply not accept the input?

Let’s try a few steps:

### Step 1: Double-check the Reference Number
- Make sure you’re entering the reference number exactly as it appears in your booking confirmation. Sometimes, it's easy to mistype a character.

### Step 2: Clear App Cache
- Sometimes, clearing the app's cache can resolve issues. Here’s how to do it on your Android device:
1. Go to Settings.
2. Scroll down and select Apps.
3. Find and select the Oman Air app.
4. Tap on Storage, then select Clear Cache.

### Step 3: Update the App
- Ensure that you have the latest version of the Oman Air app. You can check for updates in the Google Play Store.

### Step 4: Reinstall the App
- If the above steps don’t work, try uninstalling the app and then reinstalling it from the Google Play Store.

If you've gone through these steps and are still facing issues, don’t hesitate to let me know. Alternatively, if you suspect it might be a problem on Oman Air's end or a server issue, you may consider reaching out to their support at [email protected] for further assistance.
