wow, I didn't know they do that. In Czech republic this functionality works all the time, I wonder why they behave differently in these two countries.

oh no, it's only this one bank. online banking with other banks (haven't tried them all - 3 accounts is enough cough) works as expected.

it's only ironic because mbank is an internet only bank :)

Rudepeklo meant that mbank in Czech republic accepts transfer orders 24/7. I can confirm, the interbank orders will wait till the interbank reconciliation center opens, but internal transfers will be made immediately.

What's more interesting, mbank uses the same backend for pl, cz and sk. I know that it works in cz and sk exactly the way it is supposed to do. Why is pl exception?

Wow, that's interesting, but unfortunately it's not true. Maybe you got an error message because an error occurred? ;)

I tried it a few weeks ago again (I thought after 2 years they might have fixed that) - but still there was no transfer possible.
