This issue came up in I another thread over a year ago. I have a Samsung Tab S3 tablet and a Samsung Luna Pro Phone. Notification SOUNDS worked for several months. All of a sudden the SOUNDS stopped working on BOTH devices. I changed nothing on the notification settings. Double checking the settings, neither has the option to choose what sounds I want. It only offers the option to have sound -- which I do. I rely on sound notifications. I tried the solutions posted in old thread without success. Why have sounds stopped? And how can I get sounds to work again?
@Mary1387 Yesterday mine were not working. Today they are. Try rebooting your tablet and phone, I suppose. I didn't do anything for the sounds to reappear, so I can't be much help. All I can offer is a fellow host's empathy.
At this stage my devices have not lost sound notification, so I, too, am simply offering support.
However, when that happened to many people including myself, previously, I found that after a couple of weeks the notification sounds mysteriously started happening again on my phone and iPad :)
It helped, though, that while the distinct Airbnb chime was dead quiet, my incoming emails still beeped on arrival with my chosen sound...and because I looked at them asap, I was always aware of reservations straight away.
