If the O2 Venue App ticket transfer is not working, there are several common issues and fixes you should try:

1. Confirm Ticket Eligibility and App Updates
- Some tickets might not be eligible for transfer due to restrictions set by the event organizer or the ticket provider. Double-check whether your tickets can be transferred13.
- Make sure you have the latest version of the O2 Venue App installed74.

2. Email Address Issues
- You must log in to the O2 Venue App using the same email address used to purchase or receive the tickets. Using a different email, even by mistake, is the most frequent reason tickets or transfers don’t appear3476.
- If someone else transferred the tickets to you, check that you’re using the email address they entered when sending them63.
- Try signing out and signing back in with the correct email in the app’s login portal3.

3. Ticket Visibility Timing
- Tickets often appear in the app only closer to the event date—sometimes just 24-48 hours before the show345. If your event is soon and tickets are still missing, proceed to the next steps.

4. Internet and Technical Troubleshooting
- Ensure your internet connection is stable. Sometimes tickets load only when using mobile data instead of Wi-Fi1.
- Restart your phone and check for any pending app or system updates.
- If the app repeatedly gives errors or asks for login credentials (“Oops, something went wrong”), try clearing the app cache, reinstalling the app, or using a different device5.

5. Seek Help from Ticket Provider or O2
- If tickets still aren’t transferring or visible after following these steps, contact your point of purchase (like Ticketmaster or AXS) or O2 customer support for direct resolution2347. Only they can fix issues like email typos or failed transfers between ticket providers.

6. Box Office Support
- If you have a valid order confirmation but still can't access your tickets on the app, you can go to the venue's Box Office with your photo ID and the order confirmation for entry and assistance34.
