TTS not working... Can I combine android notification with TTS notification

Mobile Apps Home Assistant Companion for Android

I have a small number of automations that I would like to change the notification color and have my phone tell me as well. This is complicated by the 2026.2.2 change in format and by going from my trusty old S10+ to and S26 Ultra.

This was working on the S10 before 2026.2.2 and not working now.

I would like to get the bannner, change the icon color and have the annoucement made. This notify snippet passes yaml test, pops a notification on my phone but does not change color nor make a voice announcement.

Can I even combine them or do they need to be separate notifications?

action: notify.mobile_app_matt_s26
data:
  message: Unraid backup triggered
  title: Unraid backup started
  data:
    color: red
    vibrationPattern: 100, 1000, 100, 1000, 100
    visibility: public
    message: TTS
    data:
      tts_text: Backup is complete
      media_stream: alarm_stream_max
      priority: high
      ttl: 0

So, I did test sending 2 separate notificatioins, that does work. So, is it not possible to combine the 2?
