BUG: Writes to Large NFC Tags Fails

[shannona]

Writes to large NFC Tags never occur. No errors, no timeout, just no writing.

924 byte NFC Tags work fine at the upper end, 8 kbyte NFC Tags fail at the lower end. The exact boundary is presumably somewhere in between.

Potentially, this could be an issue with a single manufacturer. The precise cards we're having problems with are Mifare Desfire EV1 8K, part #B2004-5, or on Amazing B01FR6GZQY.

If we write an initial record on NFC Tools, they then become normally writable and readable, which suggests there is some way to do it in iOS, just not with Apple's normal tools.
