Well yes I can't argue with that,
Incidentally, with the old version of the app
You couldn't even use the long winded convuluted way to access your my giffgaff page and profile settings
On the new app, If you click "more"
They have recently added a link to go to your payback page
They may do the same with h other pages
All links accessed by clicking "more"
Will redirect to a mirror of the browser you previously gave permission to the app to use
Albeit you' don't need to then log in
