I have been traveling around in USA for 1.5 weeks now, staying at different Hilton, Hilton Garden Inn and Hampton Inn. In all places it has been impossible to log in to the WiFi. I have more than 50 nights earlier this year, and this is the first time I have this problem.
I am a Diamond member, and try first to log in with my HHONORS details. Impossible because the fields are write protected. Then trying Complimentary. Also impossible because the room number is write protected.
I have the same problem on both my iPhone 6s and iPad Air 2, both running iOS9.1
At several of the hotels they say that several guests complain about the same.
Yesterday I experimented, and I finally was able to find what caused it. I am using SwiftKey as an extra keyboard. If I remove SwiftKey, everything works fine. It does not help to switch to another keyboard, you have to emote SwiftKey.
It's difficult to say who is to blame, maybe a combination of, Hilton, Swift and iOS9.1? I don't have problems with SwiftKey in any other apps, so it must be the combination with Hilton.
Really annoying. Hilton has to look at this. I will report to SwiftKey too.
