Hello #bitcoin world

I have a question.

I have a multi-sig 2fa account on #greenwallet. With some #bitcoin in it. And let’s say this account “A”

And if I make 2of3 multi-sig account on #bluewallet with 2 other single-sig accounts.

Can I use the #bitcoin in account “A” by multi-sig way?

I’m asking you because on the multi-sig account on #bluewallet said there’s not #bitcoin in it. 0 balance.

I’m so confused right now…
