I noticed that searching for "da nang" or "danang" yields no results on the app (at least for me). Even if it autocompletes the city to "Danang, Vietnam", there are no results shown. I have to specifically search for the Hyatt Regency Danang (not two words: Da Nang... one word: Danang. I'm not sure which is correct but Wikipedia says Da Nang) in order to get anything it to show up. That can't be good for business. I originally thought that there were no Hyatts in Da Nang until someone told me there were and I searched Google maps)
