Iirc the idea was that you had to 2FA but if you couldn't for sosome reason, you could recover the funds after a timeout yourself. I forget the details.

I think that's what I did for me;
It asked me to broadcast a TX (just miner fees) to reactivate the 2FA, since the wallet was so old.
Its going through so we'll see what happens.
6 confs later and still giving me the same thing
I'll have dig into this. I'll ask some blockstream employees
