Hi , Since iOS14.6 official release , I have seen a regression in the reading of NDEF message with Type5 tags only !!! This is not a problem with an invalid NDEF or with our Tag : It was tested with many Type5 Tags and tags formatted and created with different iOS NFC apps · This problem seems to affect only ISO 15693 tags : tested with ISO 14443A, we were able to detect it So, Type5 tags are only impacted. Not Type4A. How to reproduce it : Install the iOS14.6 or iOS14.7 beta Download the coreNFC reference App from https://developer.apple.com/documentation/corenfc/building_an_nfc_tag-reader_app Use a Type5 Tag with a NDEF Formatted message Run NFC Tag reader , and see that when scanning tag, NDEF is not detected. When debugging sample code, the NFCNDEFReaderSessionDelegate is never called. Thx for your help
