There's no way to access your chat messages once it's closed out by the agent or a reservation has been cancelled. If there's still unresolved issues it's extremely difficult to navigate to the agent chat help. Also, they should verify with the hotels what's due at check in. As of now it's pretty vague or contradictory to what is listed which is the result of the hotel not updating Hopper, apparently. Be active so there's no surprises at check in. This would help immensely. Otherwise it's solid.
