Over the past few weeks, we have noticed a big difference in how well our App Clip App reads NFC tags compared to our Full App. The full app, which has the scan NFC button like all full apps, reads the NFC chips perfectly 100% of the time. The App Clip version of the same app has slowly started to be consistent in reading the NFC tags. Has something affected the App Clip NFC reading in the past few weeks after the iOS Updates? Can you tell us what we can do to make the NFC reading of the App Clip App as responsive as the NFC reading of the Full version of our App? Please advise because we want to make App Clip via NFC great, but not getting a consistent NFC read compared to the full NFC app is definitely a problem for consumers adoption.

Recently Apple updated Xcode and had one change for App Clips. For a URL to launch it needs the additional of "nullable" See link here. - https://developer.apple.com/documentation/app_clips/apactivationpayload/3580308-url?changes=latest_major&language=objc One problem. My App Clip works fine but there is nowhere in the code where to use the code defined in the link, either the previous or the new updated code. I only use NFC for the App Clip. So does this not involve NFC? It mentions payload which I'm used to hearing about with NFC chips, so that's why I'm wondering about it. I've also noticed NFC reading less consistently as background reader. Please let me know if this line has anything to do with NFC, and why my app would still work even though I don't even use this line anywhere in my code. Thank you truly and any help is appreciated. I just don't want to be missing something that might break my app in an upcoming update.

I'm looking to find a way that is private but let's us know if it is a user that has used our app clip before or is a brand new user. Similar to how you can find out how many unique users go to a website. This isn't for traking. Just for internal data to see if a new user has used your app clip of a pre-existing one. Can an app clip do this? And if yes,how? Thank you for any help you can give!
