I just got a new iPhone 6s and upon activating it I noticed the (Skype for) “Business” app being updated (v6.0.1447, released October 22nd).
When I logged in to Skype on the phone I noticed the UI being quite “funny”.
At first I thought that the “LOCID” had some reference to my account being “local” or on-premise (not Office365). But even after logging in several status tags also had text like “LOC ID unavailable” or “LOC ID missed call”. I realized that this had to be reflecting some app code tag where my locale / location (language) settings were not being recognized by the app. So I tried to change the language settings to English.
And voilá! Seems like “Norwegian Bokmål” isn’t Microsoft’s preferred language after all, even though it is listed as one of the supported ones in App Store.
I don’t know if there are other foreign languages (non-English) that are affected by this, and I expect the bug to be fixed shortly. A funny one, though!

Yea, I’ve noticed this too. I’ve also set my phone up on Norwegian, so the Skype for Business app looks weird. I wonder when this is getting fixed, though. It’s been a while now.
Tusen takk for hjelpen! Dette fikset problemet for meg og! 🙂
