NExT invalid tag error whenever I scan

I’ve had the rfid plus nfc chip in for about a week now, and I still can’t read or write onto the chip. In another thread, they said it was swelling. My galaxy s20+ has no issue sensing the chip is there, it just can’t access the information, unless it’s in nxp taginfo.
