UX: Zero points.
The transition from Transfer Wise to Wise for existing clients was poorly executed. UX rating 0.
Previously, only an email address was required in order to receive money. My sister tried repeatedly - unsuccessfully - to send me money but in order for this to be possible, I had to open a new EURO account which cost me €0,08. As soon as I had been "press-ganged" into opening an account I didn't want, her transfer went through. As you may imagine, this isn't about the €0,08.
I also use PayPal and Amex International - previously I had rated TransferWise as the least hassle, least expensive way of transferring funds. Now I will no longer be able to do that. You may not have "lost" a customer according to your user numbers, but you have certainly lost my loyalty.
