Ledger Live shows the balance I was expecting but I can't see the new address anywhere in Live. How would i access the address it doesn't seem linked to my Live app or my BTC account directly.
I don't have ledger live installed on my workpc, so i cannot give you a walktrough...
However, if you connect your ledger to electrum and enable the address-tab you should see all addresses (funded, previously funded and unfunded up to the gap limit).
This being said, as a normal user, there is hardly any usecase for this... There are only a very little amount of circumstances where you (as an enduser) would need to find out how to find the list of change addresses. As long as your balance is ok, and you don't see outgoing transactions you didn't make, everything should be fine
