Used Tripit for years and loved it. Unfortunately, the next trip to Europe has been FUBAR. Every hotel reservation, all Hilton properties, would not be entered. Same thing happened to the Viator bookings. All were forwarded from my iPad.
This also happened a month ago on a London trip.
I reported the problem and got the canned response about format change, etc.
Unless they fix this, they may lose a customer.
Cheers
