The built-in Help is in my selected language. The links in there to external content are similarly correct. Not sure why it’s picking up the wrong language for you, have you been testing the phone’s language settings somewhere else?
However. Try removing internet access and running program, and then select “learn more” info when no internet message comes up.
I suspect it is defaults to this language when no internet access was found!
So I now suspect it is a sloppy feature not a bug.
But, the no internet message was in English, just ‘learn more information’ was incorrect, which, due to previous screen being in correct language, is not correct and should be fixed to be correct.
