Bitcoin wallet app (android app).
I'm familiar with how an Hierarchical Deterministic wallet generates addresses, but I'm confused by the ever changing address of "receive coins" button in the bottom left.
Literally every time I click I'm given a different address, but the qr code in top right is always the same (and informs me it will update to new address after a transaction), but the bottom left doesn't show the actual address, only qr code, and I like to save the address each time it changes so I know which wallet it's from (so later I can confirm which of my multiple wallets will receive the payment) and also go back and check I've copied it correctly etc etc.
What's going on with "receive coins" option?
