Did anyone resolve this? Seeing the same issue for iPhone models prior to iPhone 11 only (iOS versions are all the latest for iphone 8 and X we ran tests on - it works 30-40% of the time or connection to tag is lost, tag is detected multiple times without moving it, or the select AID process is done repeatedly with success and doesn't execute the APDU command.) It works 100% of the time with iphone 11.
