Hi there! I understand you can see your bookings on the Tripadvisor Android app, but when you try to access your ticket to print it, the app redirects you to the Viator homepage instead. Let’s get this sorted out together.

First, could you please confirm a couple of things for me?
- Are you logged into the Tripadvisor app with the same account you used to book the Viator activity?
- Have you tried accessing your booking directly from the Viator app or website to see if the ticket shows up there?
- Also, is your Tripadvisor app updated to the latest version? Sometimes app updates fix these kinds of issues.

Meanwhile, here are some quick steps you can try:
1. Clear the app cache: On your Android device, go to Settings > Apps > Tripadvisor > Storage > Clear Cache. This can resolve redirect glitches.
2. Try accessing your tickets via the Viator app or Viator website directly: Sometimes the trips booked through Viator are best viewed or printed there.
3. Logout and login back: Sometimes refreshing the session fixes weird redirect loops.

If none of these work, the issue might be related to the integration between Tripadvisor and Viator accounts. I found in Tripadvisor community discussions that such redirect problems could be caused by recent changes on Viator’s backend, and contacting Viator support directly can help resolve booking retrieval issues. Viator’s help center is here: https://www.viator.com/help, or you can call them (USA & Canada: (866) 648-5873, UK: (0)20 3318 0444).

Please try these steps and let me know how it goes. If you’re still redirected instead of seeing your ticket, I can help you escalate it for further investigation.

Are you satisfied with the solution I provided so far?
