Hi,
I'm testing STMicro's M24SR64-Y based NFC tag (NFC Forum Type 4 Tag, ISO/IEC 14443 Type A) with Core NFC (iOS 11 beta 3), but it cannot be read.
(No didDetectNDEFs nor didInvalidateWithError called, while reading popup shown)
Other type 2 or type 4 tags work fine with the same application.
The tag is populated with one NDEF message, and can be read fine with Android phones.
Does similar problems get up?
