has the way you logon to the NHS app changed?
My wife's hasn't, but mine has!
NHS app now tells me I should use Chrome browser (haven't used that for years) then asks me to prove I'm human by choosing set of pictures!
I don't update android apps from the Google playstore where the app won't upload, but from the Aurora app store, and I wonder if this is "The Do Evil Corp" trying to make everyone use them.
