I believe after updating to ios15.4 I haven't been able to read NFC Tags anymore. I am on an iPhone 13 Pro.
Steps: Unlock iPhone, hold NFC tag to back of iPhone (without case or other magnetic or metallic materials nearby).Default iOS behaviour should be to read the contents off the NFC Tag and display them / do whatever action is assigned. In this case, scanning does not work, and the iPhone is trying to scan but unable. No errors show up, but it's almost like the iPhone is not scanning anything at all. No 3rd party apps work whatsoever.
Steps Taken: Hard reset, Total iPhone content erased and wiped, Updating of iPhone, updating of 3rd party apps. Nothing has worked
NOTE: Apple pay works fine. I believe software issues and not hardware.
