Setup two 2 of 2 offline multisig wallets. Put some funds in. Setup a watch only wallet as a SINGLE wallet using only ONE of the multisig wallet's master public keys.
This will create a totally different watch-only wallet which isn't multisig, the addresses wont be the same thus the "real" wallet's balance won't show up.Don't know if this is the correct forum, but I think I found a flaw in multisig. I may be wrong. I used electrum to test.
Have you tested it with wallet(s) with balance?Have you properly set you 2 of 2 wallet? Maybe you've selected 1 of 2 from the slider.
Refer to these image:
For 2/2 multisig wallet-
For 1/2 multisig wallet-
But even with 1/2 multisig, creating a watch-only wallet using only one public key will create a standard watch-only wallet.
But with 1/2, you will be able to spend using one signature.
