Unknown ISO tag and not emulating

Hey all,

On day one I read an NFC card and it detected as MI Fare Classic one and emulated successfully.
However, on day two, it stopped emulating and now is reading the card but shows Unknown ISO tag with the option to save UID and emulate UID but not like earlier where I could save the entire information.

Moreover, I tried reading my credit card but it doesn’t show the type of card, card number and other details like we see on videos. Is it restricted because of the levels of Flipper (I’m level 1) or some other external application is required to do so?

Any leads would be much appreciated.

This feature was explicitly discontinued some firmware versions ago.

Why isn’t it emulating anymore? I tried everything but nothing seems to be working
