It looks like, I had a confirmation about a friend that it worked but just for a small amount. He did the first transfert of around 100€ the 23/08 (still pending) and another of 44€ the 26/08. He received the 44€ but still not the 100€...so it looks like smallest amount goes faster, what I don't understand is that it's supposed to be a queue...so in this case they moved it manually...which is strange.
From what I read, they have an hard limit on the € they can move with SEPA using their polish bank.
It is not improbable they follow a queue, but, when the next order is too large, they fit all following smaller orders they can.
For example: if they have 999€ they can move but the next order is 1000€, they look at the following orders to fit together as much orders as they can (300+500+100+50+49=999).
I would do so
