Oh, really? I tried again and again in August but didn't try again recently. It was a multisig, 1of3, not 2FA. So you say they have fixed it? Do you also know when?
Like... a couple of days after the fork as far as I'm aware:
https://github.com/fyookball/electrum/issues/67Basically, they had some issues with signing when using MultiSig, but I'm fairly certain it got sorted out... It was just the issues with 2FA that kept going and going... mostly because people were unable to read

If multisig signing wasn't working, then the restored 2FA "workaround" probably wouldn't be working (as that has to use two sigs to sign a transaction)
So, theoretically, you can either just load up
a copy of your MultiSig wallet in ElectronCash, or you can attempt to recreate the MultiSig by creating a 1of3 and using the xprv and two xpubs from your Electrum MultiSig wallet.
