I don’t think this is a bug report per se, more a feature disparity between iOS and Android, but I thought I’d log it here.
On iOS you can see the “raw” data for direct debits at the bottom of transactions, similar to the way you can see raw merchant information for card purchases.
On Android, while you can see the raw card transaction details you can’t see the raw direct debit details. This is particularly a problem when having frustrating conversations with support.
(I’ve also added to the platform parity wiki).
