Can you reliably get a full memory scan each time with TagInfo? Getting it to register is not the issue, the issue we’ve seen is that the tag will begin to read, and then the process is aborted. This is a problem with Android, not with the chip itself or even the coupling.
What phone do you have?
This means that during the attempt to cryptographically verify the chip’s authenticity, something broke and the attempt did not succeed. This happens as well on my Pixel 2. Very irritating.
