Thank you all for your kind time.

well thank you so very much, this solved my problem. But I still have few questions to understand it completely and I'll be more than happy if you can help me out further.

1- after creating a new wallet using 1 wallet with seed and the other one with master pub key + attaching trezor device, now when I go to send button and hit sign in my trezor signing pops up and when I sign it from trezor device it just simple send payment without asking me to sign from the 2nd and from the 3rd owners?

2- in future what if these 3 owners (2 Computer wallets + 1 Hardware device) get apart ... how can they restore this multiple wallet if they don't have complete 3 wallets on hand? let's say I lose my hardware device but still have 2 wallets with seed and master .. how can I even restore my wallet without hardware ..? on 3/2 wallet creation it ask must to restore from all three otherwise it won't work ..?

3- I tried to restore my 3/2 wallet by using 2-2 multisig wallets using 1seed + 1master (without hardware)... and seems like it doesnt' restore the actual wallet .. it is just a new wallet of 2-2... how can we restore these kind of wallets ..?

4- Multisig only works for Bitcoin. What if I can use a hardware Trezor device which has many other crypto assets like ethereum and other assets, would my other assets would stay on the same hardware wallet ..? I mean whenever I need to transfer/access Bitcoin I use multiple using electrum .. and when I need to access other assets I use trezor suit to access them .. is it possible to use one device for two purposes ..?

thank you for responding

I've 2 seed phrases of the wallets I created on my laptop using electrum and I've attached 1 Trezor hardware wallet.
when I click on send BTC .. it just ask me to connect my trezor wallet and when I connect it just don't ask for other signs neither I see broadcast button.
and I enabled Send Consign button, it sends but I don't know where and how to receive the second transaction consigning signing message.

Hello Everyone,

This is my first time I'm using Electrum Multisig wallet. I've created a 2/3 multisig wallet by using 1 Trezor Hardware wallet and 2 Electrum generated multi-sig wallets (I created one and then close the windows without adding other 2 consignees ... and on the second attempt I created new wallet and restored the old multisig wallet I cancelled by using master pub key and attached my hardware wallet to make the 3/2 combination) ... but now whenever I transfer funds from my wallet it only get signing command from my hardware wallet and Sign & Broadcast button grays out .. and status of the transaction become Partially Signed (1/2) and I don't see how to Sign my transaction from other two wallets I created on my laptop .. I even tried to create and new wallet by importing one of the created wallets but that wallet shows nothing ...
