Not exactly. to put it short, the OP actually did the QA person's job, by showing and proving to the bank/managers at the bank that it is reproducible. that actually helps them instead of inhibits them. No contradiction there at all.
Again, if the intent of the reproduction is not malicious, there is no problem in reproducing it for the managers to see.
BL.
It isn't the OP's role or business to do the QA person's job and over an issue where someone foolishly attempted to use Apple Pay in a bank.
