That is funny........I have about 100/0 chance of receiving communication, so I guess you have been unlucky. I always message the property with my flight details and expected time of arrival and then update them when I am enroute so it is fresh on their minds when I arrive. For the odd time I am not upgraded before check-in I have been through the chat by saying "any upgrades would be appreciated."

It has also been lifesaving for assistance with last minute IRROPS. As mentioned before, my QF F flight to SYD was delayed 24 hours. I was already checked-in at the Marriott at Circular Quay but still in DFW. When I advised them I would be delayed, they shortened my reservation by one day without penalty. When I arrived the day after, I was upgraded to a Junior suite and checked into my room at 7:30 am and had lounge access for breakfast on the day of arrival.
