On simulator, everything works fine. But when I run on an iOS beta 3 device, the UI simply doesn't change. I just see the one button stay there. Logs show the below upon every click. I know there's the expected System UI with "Hold here to present" based on the simulator, but I can't see it on a real device. Is there some Terms & Conditions thing I should expect, maybe? Please advise. Thanks. . . . [for reference, the below are the error logs in Xcode] An error occurred while reading a mobile document: The operation couldn’t be completed. (ProximityReader.MobileDocumentReaderError error 6.) serviceUnavailable Could not create identity session due to: [ Error Domain=ProximityReader.IdentityReaderErrorInternal Code=15 UserInfo={NSDebugDescription=, code=} ]

I am attempting to implement the Tap to Present ID (Data Request) feature and am wondering if the Data Request will succeed without a reader token. From the wording in the WWDC video (31:50 in WWDC2023-10114 video), it sounds the reader token is necessary, but the example is building off of the previous MobileDriversLicenseDisplayRequest example where the the reader token was used only for the branding to be displayed. In my app running on Simulator, I'm able to get the placeholder data to return from a MobileDriversLicenseDataRequest without using a reader token. Since I'm unable to test this on physical device (I don't live in a state that has Mobile ID's), I'm hoping an Apple engineer can comment on if the reader token is required strictly for the branding to be presented, and not for the Data Request itself to succeed. Thank you.

The talk tagged below mentions sending order packages by email. I just tried sending a signed package from the sample packages that were released last year - and viewing the email on my iPhone running iOS 17 beta 1. Here it does not open in Wallet, but I suspect this is just a beta issue. My actual question is: Will it be alright for any system to attach an order package to an email? I am working on a POS-system that is iOS-based, and I would like the end customers to be able to add their orders to Wallet. Can I add an order package - or a link to an order package to my receipt emails and have those be added to Wallet? Or does Apple Pay somehow have to be involved? Can I serve an order package from a webserver? Could it be added to wallet directly from a QR code while the customer is still in the store?
