Hi there @Samander, Thanks for reaching out, and welcome to the community. Sorry to know about this issue on Snooze notifications on your Android device and thanks for sending a diagnostic report of your Sonos system. It detected a lot of issues on the diagnostic information, 

Interference on Station Mode, Audio Playback Failure - Transport Errors. Audio Dropout Detected. I want to ask some questions to check further on this issue. 

• When did it start happening that it doesn’t show the Snooze notifications?
• Have you tried it on another Android device if the same thing is happening?
• Are there any changes made on the settings on the Sonos App or updates before this issue happened?

Answers to these questions will help us determine where the issue is coming from. 

Keep us posted on how it goes and we're here to answer any further questions you have.

Hello Simon,

Thank you for reverting.

Could you please shed some light on the diagnostics outcome? I’d like to understand what exactly is happening and why. I’d like to fix all issues since the app is very inconsistent at my end.

To answer your questions, snooze lock screen notifications never actually showed up on my screen. I now have two Sonos products in the same room (a Play:1 and a Play:5 Gen 2). The alarm, however, is only currently configured for the Play:5 Gen 2 since it is right next to my bed.

Last night, I tried accessing the Sonos app settings from the Android apps page on my phone and found that the Android system automatically (and by default) optimizes battery usage. I toggled this option to off so it doesn’t optimize battery usage for the Sonos app (and doesn’t put it to sleep). This seems to have (temporarily) fixed the issue since I got the snooze notification this morning, but I cannot bet on getting it every time. Let us work on permanently fixing this issue by referring to the diagnostics report outcome, please.

One more thing re alarms: The chime sound plays instead of the radio station. Please help.

I ran a diagnostics report as soon as I snoozed the Chime sound (which was supposed to be a radio station) this morning. Confirmation number is 99516818.

Hi @Simon B could you please get back to me?

Happy new year.

Hi there @Samander, thanks for the update and the information and diagnostic report that you’ve sent. Upon checking, there were alarms set at 06:30, 06:40, and 06:50. But can’t see any reason why the notifications will not show up. You can also check on this thread about the same issue. We’ll take this further. We may need to do screen share or remote access to your device so that we can check for the settings on the Sonos App, I'll ask you to kindly contact our phone support team for further assistance and more in-depth troubleshooting steps.    

Keep us posted on how it goes and we're here to answer any further questions you have.
