Hi @michelangelo_is_the_best_tmnt, thanks for checking and sharing your findings! Interesting observation regarding Mastercard and Cembra, that definitely sounded like a plausible lead. In my case, though, the Mastercard is currently working fine. I’ve noticed that the issue appears intermittently and doesn’t seem to be tied specifically to either Mastercard or Visa. There are times when the error occurs regardless of the card provider. Appreciate you digging into this!

@DTS Engineer I reported the bug FB21543035 and attached a demo project.

Unfortunately, this is still not working reliably on iOS 26. Timeouts occur frequently. In addition, the trigger still fires for declined transactions, and Apple Pay transactions for Metro result in an immediate error.

Hi @ArnoldM2 would you mind upvoting and leaving a comment on the forum to help boost the issue and get Apple’s attention? The more visibility we can get, the better the chances for a fix. https://developer.apple.com/forums/thread/765516 Thanks for your efforts!

Test project added to demonstrate the issue. https://feedbackassistant.apple.com/feedback/14828592

Hi, @nimtech the issue you're encountering is related to the card provider timeout. However, the trigger should still be able to complete even in the event of a timeout but does not. Unfortunately, the problem persists in iOS 18.3. If there are any updates or solutions discovered, I'll be sure to share them here.

I encountered the same issue. The didMigrate method was only triggered after switching the initializer.
