Using ASN here too, they threatened to close our account if I wouldn't reply within a couple of weeks. Saw it too late as we were on holiday. It made me quite nervous, as there was no way I could reply in time. Of course it would likely be the same for any other bank.
They never denied any transaction, but I never transacted fiat with Binance, only Kraken and Bitvavo.
The handling by the aml department was a fucking mess by the way. They lost the private documents I sent them using their highly secured "black box", as they called it. Later they somehow found back the documents somewhere on another PC, while they initially promised the documents would never leave their "black box".
Incredible.

I personally prefer to use third party bridges, these are much faster and generally cheaper to use. But of course always make sure they are legitimate first, several of those bridges are listed on the Base website.
