Detect reader not collecting nonces

I have a nfc card with some sectors my Flipper Zero could not read. When using the detect reader function to gather some nonces necessary to get the missing keys from, none would be collected. Even with repeated tries it would only tell me to move the Flipper to the reader and then back again and so forth without the nonces count increasing.

In the docs it says that if the nonces are not increasing after mutliple attempts, the reader is not trying to authenticate the card. But why? What can I do in a situation like this? Or am I doing something wrong?

Thank you in advance.

Same here, have you solved this issue ?

Sadly no. Later on it started to give feedback like it works as it should but couldn’t collect any nonces though.

For me Detect Reader does gather 10 nonces and then says to next use Mfkey32. But Mfkey32 then says no new nonces found, and I can’t see any way to view them, save them, or get them used either on Flipper or with the Android App.
