📝 Original message:Hi Michele,

You are seeing this discrepancy due to the address types in use. addmultisigaddress uses the default address type of the wallet, which is p2sh-segwit. createmultisig uses a default address type of legacy. To have createmultisig get addmultisigaddress's result, you need to add the string "p2sh-segwit" to the end of your command. To have addmultisigaddress get createmultisig's result, you need to add the string "legacy" to the end of your command.
