Contrary as I am, and despite having all those, I feel inclined to wait and see. I'm only using the account to store my lump sum for visa extension purposes, so a freeze won't cause me any issues. I'm rather fascinated to see what happens.
This Facebook Group has over 100,000 members and from the replies 3 have had their accounts frozen without using the banking app. If the requirement that banks check their customers is correct, the number ought to be rather higher. Not sure that I've learned very much, other than KYC isn't a fast food establishment ;-)
Three comments in 5 hours, suggests that the banking app underlies the BB problem. I personally have had no problems with BB. I hope that remains the case.
I don't have a DTV. Been here 20 years. I still have no idea what a DTV is. I maintain in excess of 800k. I did mention "lump sum" in the original post.
