Perfect, thank you, I didn't know about the cold side loading options, I've got zapstore and side loaded as a normal hot phone

Agree, multisig is very complicated

But I have to say , I had the 3 phones setup and then created a standard watch wallet on the chromebook by importing the zpubs

Created the tx on watch wallet, signed with 2 cold phones and broadcast with watch wallet

Very cool 😎 and to think electrum has been around since the very early days blows my mind
