Hey, apologies for any inconvenience caused 
Unfortunately, some banks find it a bit confusing that we have a Lithuanian IBAN with a UK BIC. Not impressed by old school banks 
We’re working on launching UK IBANs asap so we can resolve these issues 
If your bank is unable to proceed with the transfer please use our EUR pooled account.
Please do not hesitate to contact me directly if you have any questions!
Best,
Andreas K.
