We are attempting to integrate the Apple Pay service into our website and have successfully verified our domain with Apple manually. However, we consistently receive an 'ApplePay reverify failed' email a month before the expiration time. Upon checking, we updated the SSL certificate for the domain before receiving the email, and the link still works fine in the browser. We would greatly appreciate any feedback from someone who can help us with this issue.

Since integrating MapKit JS, we’ve begun receiving production error reports with the following message: Uncaught DataCloneError: Failed to execute 'postMessage' on 'DedicatedWorkerGlobalScope': ArrayBuffer is not detachable and could not be cloned. It appears that MapKit JS’s internal worker occasionally calls postMessage() with an ArrayBuffer that cannot be detached under Chrome 120+. This causes the structured clone to fail and the error surfaces uncaught from within the worker. MapKit JS Version: 5.79.109 Browser: Chrome 120.0+ OS: Windows 10 Is this a known issue with MapKit JS? If so, are there recommended workarounds or planned fixes?
