@csdevfr Thank you for the recommendation. My initial message included a link to the report with the sysdiagnose. For context, here are my current setup: • TestFlight builds. • Production cards. • Apple certification stage - the step where you need to select a lab for certification. Our card provider insists that the encryption API is working as expected and that their SDK relies on the same implementation. Unfortunately, they haven’t been very responsive. I’m hoping to receive the nonces from Apple so we can confirm whether the issue is on their side and have clear evidence to ask them to thoroughly verify everything.

By the way, I’m very sorry for spamming replies. The website wasn’t working properly and kept returning an error when I tried to post, so I didn’t realize my messages were actually going through.

Hi @csdevfr , Thank you for sharing this. If you manage to resolve it, please share the solution here as well; it would be very helpful.

@DTS Engineer Thank you so much for your reply. Could you please share the nonce that was initially provided to the "add payment pass request", as well as the nonce included in the encrypted card data? Our provider insists that everything is functioning correctly on their side, so we’d like to review and compare the logs from all parties to better understand where the discrepancy might have occurred. Would it be possible for you to provide this information?
