Bug in screen transition !?
The latest version as of today seems to have a bug or usability problem ... while reserving new hotel and try to remember existing reservation, I encountered unexpected log out.
I needed to log in again several time. Suspecting certain screen transition caused such error !?
Since operation itself was common for whom he has multiple reservations and try to book new one, hope itll fix soon.
