I also received the reply indicating the new shareholder OBC procedure when I e-mailed my redacted brokerage statement and the request form to Princess. I installed the app on my phone, uploaded a PDF of the statement and the next morning I received a message that it had been validated. I then went into the app to redeem the OBC credit and got a confirmation that within 5 business days the credit would be applied to my booking, or they would request more information. I didn't have to enter any login details for my brokerage account.
