Notify Group no longer works

Hi everyone, wondered if anyone has a solution to this issue. My notifiation group config stopped working at somepoint. If I go to developer->services and send a notification direct to notify.mobile_app_jon_s_s24, it works, but sending it via the notification group does not. I currently only have one device in the group for troubleshooting.

notify:
  - platform: group
    name: "mobile_devices"
    services:
      - service: mobile_app_jon_s_s24

Need more info. ‘Does not work’ is never enough.

Please show the automation and the logs.

Create your group like this

notify:
  - name: ALL_DEVICES
    platform: group
    services:
      - service: mobile_app_jon_s_s24

My test was successful.

@jpfeifer14 I wonder if this was helpful (not for me), I’m having exactly the same problem.
After installing 2024.5.3 it stopped functioning.

In the above example: notify.all_devices is simply not created.

The only (relevant) error I can find is this:
2024-05-23 18:42:40.762 ERROR (MainThread) [homeassistant.components.mobile_app.notify] Internal error encountered. This message is generated externally to Home Assistant.

I see the same problem, but it only seems to affect Android devices, iOS devices added to group will receive the notifications just fine.

You may want to share some details about the devices you are experiencing trouble with. I just tested my group notifiers and all android devices are being notified as expected, so this may be limited to specific models, OS versions, or settings.

In this specific case it’s a Samsung Tablet A8 and a Samsung S22.
