Nfc_OnMessagePublished callback has empty tagInfo

[giovanelli-michele]

Description

I am developing an app that reads/writes information on NDEF Mime tags. The app runs without problems except when running on Android 13 devices.

On Android 13 device, when I try to write info on a tag with the CrossNFC.Current.PublishMessage(tagInfo) method, and wait for the Nfc_OnMessagePublished(ITagInfo tagInfo), I receive in the Nfc_OnMessagePublished callback an empty tagInfo.
The IsEmpty field is set to true and the Records array is empty.

However, debugging the code when writing the tag (when calling PublishMessage(tagInfo)), I checked that the tagInfo is not empty. Similarly, if I check the tag content using any NFC reader (NFC Tools Android app), the tag turns out to be correctly written.

When trying the same app on a lower Android device, the problem is not encountered.

As a workaround, I saved in a variable the written tagInfo, and used the variable instead of the callback parameter if the parameter is empty.

Steps to Reproduce

1. Perform a PublishMessage(tagInfo) on a tag and log the parameter of the Nfc_OnMessagePublished(ITagInfo tagInfo) callback
2. Check that the received tagInfo is empty (IsEmpty field is set to true and the Records array is empty).
3. Check that the tag is not empty with a NFC reader

Expected Behavior

Nfc_OnMessagePublished(ITagInfo tagInfo) callback method should have the tagInfo filled.

Actual Behavior

Nfc_OnMessagePublished(ITagInfo tagInfo) callback method provides an empty tagInfo (IsEmpty field is set to true and the Records array is empty).
