Hi! I understand you're getting an "Access Denied" message when trying to open a book sample from your BookBub daily email on your iPad. Let's work through this together.

First, a few questions to clarify:
- Are you opening the sample through the BookBub app or directly from the email link in your mail app/browser?
- Have you tried opening other samples from previous emails—do they work fine?
- Is your BookBub app and your iPad software fully updated?
- Are there any restrictions enabled on your iPad, like Screen Time content restrictions?

Based on common causes, here are some steps to try:

1. Check Content & Privacy Restrictions: On your iPad, go to Settings > Screen Time > Content & Privacy Restrictions. Make sure any restrictions on websites or apps aren't blocking BookBub links.

2. Update apps and iOS: Make sure your BookBub app and Apple Books app (if you use it) are updated via the App Store. Also, check for any iOS updates via Settings > General > Software Update.

3. Try opening the link in Safari: Instead of tapping the link in the email directly, press and hold the link, then choose "Open in Safari" to see if it loads properly.

4. Clear Safari cache: Sometimes cached data causes loading issues. Go to Settings > Safari > Clear History and Website Data.

5. Sign in to BookBub: Ensure you're properly signed into your BookBub account in the app or website. Sometimes not being signed in can cause access issues1 2.

Would you mind trying these steps and letting me know where you get? That way, I can help you further.
