**Last working Home Assistant release (if known):**
Unknown, it's been an issue for awhile.

**Description of problem, include YAML if issue is related to notifications:**
I've had this issue for quite a while and just recently found it to be related to the `persistent` setting.
All notifications with `persistent: true` won't show the title or message on the screen when it pops-up. There is a slight difference between devices.

On my phone with it locked and the screen off it'll turn on the screen and show the message only as "Home Assistant: New Message". If I turn the screen on and look the message appears just fine, as it should. It's only during the screen off/locked state when it pops-up it doesn't show the details. Permissions match all other notifications where this does not happen. It acts normal with `persistent: false`.

On my watch it does similar, though instead of "Home Assistant: New Message" it's just "Home Assistant: Home Assistant" but when I go to check the notifications it isn't there at all. All persistent notifications are missing from my watch notification area.

**Companion App Logs:**
I need time to scrub my phone log of sensitive information...
I don't know how to get logs from Wear OS.

I am triggering the notify service via Node-RED. This is what the JSON of the node looks like:
