Sorry to moan again, but …
The map in the Tfl “Oyster” app isn’t exactly bang-up-to-date.
I have spoken to the Product Manager and a map refresh is in the backlog.
There are some priority upgrades that need to be completed before this is launched though.
Five months later and it’s still the same Dec. 2019 map!
The map update was blocked by changes that needed to be made for the authentication systems used by the app. The map refresh is now due in September.
