it shows "generating keys" popup for half a second then closes. no key generated at all. Tried burst/incr FF 00 00 00 AI AI. The card UID shows in the console. I used either internal NFC or acr122u and they both scanned the card in the app. OnePlus 7t pro rooted/nethunter

Yeah I like the app I just didn't understand it at the time that I purchased it and got myself anbut as I understand it a little bit better now and what was going on to the national security prep list and being a national security agent on how revenue works an ignorant mistake I made know what you're doing if you're operating it.
