I have now twice had the problem with app that it sets my check in time to 12 hours earlier. I select 21:30, a bit later the app shows that as 09:30.

First time I was fairly certain I had selected 17:30, but coming to the RC Berlin they had had a room ready from 05:30, that was the notification they got. This time I made 100% sure I selected 21:30, but just had to call the hotel to let them know that I was not coming 09:30

Before calling I tried updating my arrival time to 21:30, but everytime it switched back to 09:30.

Anyone having the same problem?
