Good that EE TV have provided some updated documentation/guide for the box pro but the author got this bit wrong unless we can now choose which apps to have on the Box Pro.
"You can add new functions to your set-top box by installing apps from the set-top box app store."
the advice given will result in launching an (already installed) app.
There is also some confusion surrounding "My TV"
The EE TV app on the box pro has a MY TV section which is what seems to be described in
https://deviceguides.ee.co.uk/ee/tv-pro-proprietary-os/functions/using-my-tv/
However users of the TV Box Pro has My TV prominently displayed on the box home page as the icon used
for the RECORDINGS & WATCH LIST area.
I see no guidance explaining for using/managing the Box Pro MY BT (Recording/WatchList/Scheduled screens). All the guidence seems to suggest that recordings are controlled within the Guide alone)
In using MY TV prominently for two different purposes (ie in Box Pro Home screen and within EE TV app when launched) there is likely to be confusion.
Thanks for highlighting @zulu17 - picking this up with the teams who look after the device guides.
