ledgerblue version ledgerblue==0.1.48
Device

Product is genuine
SE Version 2.1.0
MCU Version 1.1
MCU Hash 04302e3131

Does anyone know what that could potentially be? It goes through the secret negotiation and then drops in createAppNoInstallParams. Is is some sort of incompatibility or am I passing bad args?

Running on Mac OS

Thank you in advance!
