Hello,

I just created an Electrum multisig in Tails (totally offline), and one of the signatures must come from a Trezor one. When I try to sign, there's a message: "missing previous tx".

Can someone help me about this error?

I was using Electrum 4.0.9 and now tried 4.3.4. Same problem. All the process was done totally offline, I don't want to go online to sign anything.

I try to sign with the Trezor first, or last, or in the middle. Same problem. All the signatures go well except the Trezor's.

The wallet created just has master keys for the other signatures, except for the Trezor's.

Thank you.
