A. 1. Verify Ticket Type: Ensure that the tickets you are trying to use are indeed valid for the museum you are visiting. Check the museum's website for accepted ticket types. 2. Purchase Directly from Museum: If the app tickets are not accepted, consider purchasing tickets directly from the museum's website or at the entrance.

B. 3. Keep Printed Copies: If possible, print your tickets or save them as PDFs to show at the museum.
