HA Notifications stopped including image - any suggestions?

I have had an automation set up that sends a HA notification to my iPhone that used to include a still camera image of our porch when a package delivery is detected by the Unifi Protect front door camera. It was working fine until very recently (exact date unknown) when the notification stopped including the image with it. The notification is received on my iPhone, just no still image attached to the notification. My iPhone 17 is on the same network as the HA. Part of the automation includes sending the still image of the porch to our Google Home Hubs, which continues to work fine - image of porch included and announces package at the front door. The only the piece of the automation that suddenly stopped working is where the HA notification does not include the still image with it. I have a similar automation set up for when someone rings the front door bell and it’s experiencing the same issue. I think the only recent changes are a new iPhone (which gets the HA notification) and updating HA system software. Here’s the YAML for the notification:

device_id: d26d66c925c4dd1459cc3bec029ef7a8
domain: mobile_app
type: notify
message: Package is at front door
data:
  attachment:
    url: /media/local/front_door_package_camera_tmp/front_door_package.png
    content-type: png
    hide-thumbnail: false
title: Package

I’m wondering if something changed with how HA handles the image in the notifications and I need to make a change to my code for it. Or, perhaps there is something else I need to adjust. Thanks

Nevermind. Turned phone off for a bit, turned back on, and now images are showing up with the HA notifications. Also, closed the HA app for a bit and reopened it. One or both of those triggered things to start working again. Sorry for creating some clutter.
