Norway isn't part of the EU and should therefore be listed like Switzerland, with its own flag.
Add the flag of Norway near the one from Switzerland.
Difference between Norway & Switzerland: Norway is part of the EEA but not of the EU, while Switzerland is neither part of the EEA nor of the EU. But I don't think that the app is referring to the EEA with the European flag, or?

@Ein-Tim
I interpret the flag to refer more to the country / country group running the gateway rather than a political category.
It is also a poltical category because norway is member of the e-health group of the eu and is accepting the guidelines of the e-health group

Thanks for the answers @MikeMcC399 and @thomasaugsten!
Seems like this is not the most obvious implementation (users won't think about the e-health group when they see this flag but rather about the European Union) but is ok for now.
According to eHealth Network "The Network is composed of members coming from all EU Member States and Norway (observer)."
