grrr ... so I was testing some locale changes for TB health checks: namely that the languages are exactly what they should be: i.e supported, correct case, correct order. And that the locale matches (language !== locale is not good enough, e.g. `it-IT` language uses `it` locale), also correct case. I am excluding android for now as I believe that we don;t have parity and/or there is something going on with case (e.g. en-us, or even what is used, e.g. en vs en-US .. blah blah) So I was messing around adding languages. Whilst in en-US, I added French, then Danish  and when I added Danish, I got the apply and restart, so I did - and this is what happened  so my locale matches Danish, but my languages were never set correctly. The languages in the UI are as per the first pic So now I decide to go back to en-US and replicate my steps for you, so I choose to change to english and apply and restart and this is what I get - NOTE I cannot remove `Dansk` or `Francais` ... and after some more fiddling, can't remove `Espanol`, `Cestina`  So not only does the UI become borked, but looking at the first image, we fubar the fingerprint. I think when we apply a language change we need to properly reset the UI and navigator properties **edit** AND locale cc @pierov
