I do not receive last minute updates on my phone. I have my correct information in the Contact Me page. I receive the "Time To Check In" information 24 hours ahead of the flight, but nothing else when gates change or when flights are delayed/canceled. I also receive no email, but that is unimportant to me.
I have "Use the above preferences for both advanced updates and last-minute updates" checked.
I have a Verizon cell-phone number
This has been going on for over 2 years. I have gotten tired of complaining by calling the help desk, they inevitably tell me to delete and re-add my information, which just kicks the problem out a few weeks more. I did get bumped up to a higher level of support once but that did not help.
Does anyone else have this issue? (looking for company for my misery

)
Does anyone have a solution? (looking for an end to the misery

)
on edit: I just noticed that under Contact preferences it says "everyday 12am-12pm". But this is not a value that can be updated. Hmmm....
