It’s a samsung note 20. I get the same message in nfc tools pro, nxp tag info, and nxp Tag writer. (Error invalid tag). It hasn’t shifted I can feel it and see it if I push on one side. The other Xnt tag I have works just fine. And this one worked yesterday. It’s just my digital business card, the data set was written with nxp tag writer. I think I’m gonna have to pop it out and send it back to the bat cave.
