Of course that has worked before. I have used CX’s mobile boarding pass on my iPhone for a long time and it worked perfectly: updating of seat number (should you wish to change your seat selection after check in); updating of class of service (op upgrades); updating gate number assignments and subsequent gate changes; updating of departure time (should flight be delayed): etc.

Now, nothing updates. Even if you pull down the screen to refresh, the screen just stays the same.

To update the pass, i now have to add it in Wallet again every time.

By the way, I just checked in for a flight this morning, and talked to the check in staff about the mobile boarding pass issues. They are aware of it. The lady even told me that some mobile boarding passes they have seen had the QR code missing.
