Hi there! I understand you're having trouble loading a PDF document within the Golden 1 app on your iPhone. I'd like to help get this sorted out for you.

Could you please tell me a bit more to narrow down the problem? For example:
- Does the PDF fail to load at all, or does it display partially?
- Are you able to open other PDFs outside the Golden 1 app on the same iPhone?
- Have you recently updated the Golden 1 app or your iOS version?
- Is this issue happening with all PDFs or just a specific document?

Meanwhile, here are some general steps that often resolve PDF loading issues in apps on iPhones:

1. Force Close and Reopen the Golden 1 App
Double-click the Home button or swipe up from the bottom (depending on your iPhone model) to open the app switcher, then swipe up on the Golden 1 app to close it. Reopen it and try loading the PDF again.

2. Check Internet Connection
Ensure your iPhone has a stable internet connection, as the app may need to download the PDF from a server.

3. Update the Golden 1 App and iOS
Go to the App Store, check if an update for the Golden 1 app is available, and install it. Also, make sure your iPhone’s iOS is up to date under Settings > General > Software Update.

4. Restart Your iPhone
Sometimes a simple reboot clears temporary glitches affecting app performance.

5. Clear App Cache/Data
Although iOS apps don’t generally have a manual cache clear option, uninstalling and reinstalling the Golden 1 app can help clear corrupted temporary data.

6. Try Opening the PDF in a Different App
If you can download the PDF via the app, try sharing it to another PDF reader app (like Apple Books or Adobe Acrobat Reader) to check if the problem is specific to the Golden 1 app’s internal viewer.

If none of these steps fixes the issue, it might be related to a recent update or a server-side problem that Golden 1 is working on. I can check for any alerts from Golden 1 about this if you want.

Let me know what you’ve tried so far or if you want me to guide you through any of these steps!
