Can i no longer use the old Notify anymore like cells?

@ginandbacon
i figured it out in the end.. was getting frustrated how it works 1 min and totally broken later.
so its Not and Entity and its not a Service

its actually a Device so you gotta change from entity to Device to fix it in the end.. i didnt see it as i wasnt editing through the UI and when i did i saw entitie devices areas labels
it will also say 1 entity
but thats how i figured it out in the end its a Device now where in the past it was a entity when i had setup the automation a few years ago.

also seems the party thats being depreciated is the action
called

Perform action 'Send a notification with text_cell_notification'

so you need to set it to

send a notification

and then you gotta choose “Device” so the example they gave where it says your format is being depreciated in 2027 is wrong
cuz they showed

entity_id: notify.text_cell_notification   or   smtp.text_cell_notification

well thats wrong you cant do it in the yaml you gotta do it in the gui..
and the yaml looks like this

          - action: notify.send_message
            target:
              device_id: 02520ac22eb70eb433f829e44d8d8069
            data:
              message: >-
                Gifts Have Been Delivered '{{
                as_timestamp(states('sensor.date_time_iso')) |
                timestamp_custom('%I:%M %p') }}'

was frustrating trying to figure it out when i followed there exampl they told me how to do the new format.. yet its not really notify. as an entity.. but a device and you gotta use there device code

so damn confusing..
but its fix now.. it feels like how something works fine then they find a problem to make it worse lol
but after a headache of rolling back and updating and nothing working that seemed to fixed the issue now

so fingers crossed it will work.. with there new way.. as the example it gave just made things worse lol

here is how i found it

No, you don’t.

If you want to, you can use the Device as a target… for that matter, you can also target Areas or Labels if your notify entities or device have been assigned those.

But you, absolutely, can use the notify entities from SMTP (aka the Recipients) as targets:

action: notify.send_message
target:
  entity_id: notify.email_drew_gmail
data:
  message: test

One important difference is that using a Device target will send the message to all the Recipients for that integration service instance. If you want to choose specific Recipients, you have to target the Entities.
