Fix the app! This is ridiculous! You can no longer use the digital key and you can't check in or out. You can't book anything on the app. You basically can't do anything with the app anymore. If you want to do anything you have to log on to the website. I think in today's day and age this is bein being ridiculous. I'm a Diamond member and stay at your hotels constantly and this is just beyond frustrating at this point that you've not even done any updates to fix these issues. Disappointed in you Hilton!
