I really doubt that is the driver behind the “hold up” to be honest. Besides, in today’s banking world, asking customers to wait 3 days as part of some sort of clearance mechanism is a little outrageous considering you can ping tens of thousands around the EEC that will clear rapidly. Can you imagine if the best Amazon Prime could manage was 3 days away delivery!
My guess, it was May weekend! Yesterday wasn’t a Swedish public holiday but who knows, perhaps the guys at Elektron took it easy for the day (or to celebrate the launch).
Patience!
