Hi there! I understand you're having trouble with the "full consent before continuing" prompt while trying to complete your Passage Contract through the Princess Cruises app. Let’s get this figured out together.

First, just to clarify:
- Are you using the Princess Cruises app on your Mac? (Since you're on OS X 10.15.7, I want to make sure you're accessing through the app or a browser.)
- Can you describe exactly what happens when you try to give full consent? For example, does the consent box not appear, or are you unable to interact with it?
- Have you already tried refreshing the page or restarting the app?

Meanwhile, here are a few steps that might help:

1. If you’re using a web browser on your Mac:
- Try clearing your browser cache and cookies. Sometimes old data can interfere with consent prompts.
- Make sure your browser is up to date. Safari on macOS Catalina (10.15.7) is supported, but updating to the latest version possible on your OS will help.

2. Check your browser settings to ensure that JavaScript is enabled, as the consent box might rely on it to display correctly.

3. If possible, try completing the contract on a different browser. For example, if you're using Safari, try Google Chrome or Firefox, which are compatible with macOS Catalina.

4. Disable any browser extensions temporarily, especially ad blockers or privacy tools, as they sometimes block pop-ups or consent dialogs.

5. If you are using the Princess Cruises app on your Mac, try uninstalling and reinstalling it to ensure you have the latest version.

Let me know how these steps work out or if you see any error messages during the process. That way, I can guide you further!
