Tagmo: Tag lost error. Writes NFC tags improperly, however still writes them but isn’t an amiibo?

Описание

Hi here's some context; I bought 50 blank NFC tags/cards, I have successfully written .bin files onto 17 of them mid last year (2021) which works on the Switch. This year I tried to write some more tags and this is what happens repeatedly; firstly I scan the blank tag on Tagmo to make sure it's blank and readable. Then I download a .bin file and put it onto my Oppo phone via my laptop. Then using my phone now, I write the .bin file onto the NFC tag but then this message pops up; 'Error while writing main data (stage 1) java.io.IOExeption: transience failed' or ‘tag lost’ and then it brings me back to the home screen. However, when I go to scan that same tag again using my phone, it actually identifies the tag as the .bin file I'd just tried to write. So then when I turn on my Nintendo Switch and go into a game and try using the supposed amiibo, it says something along the lines of 'This is not an amiibo...'.

So I have corrupted 5 tags now using different .bin files. I've deleted and redownloaded Tagmo versions 2.6 and 2.7. I've also disabled the NTAG215 validation (tag verification). The unfixed and locked Key is in place. I can't work out why it's not writing tags properly but at the same time corrupting them so they are written by something but it's not an amiibo...

Does anybody know what could be the issue?
