Home Assistant Companion App ignores url parameter

[ddebarr-gh]

Model Name: iPhone 15 Pro Max
Software Version: iOS 26.1
App version: Home Assistant Companion 2025.12.1 (2025.1546)

Home Assistant OS Core version: 2025.12.4

If the Home Assistant Companion app is already open, the notification test shown below works; however, if the Home Assistant Companion app is not already running, it just opens the app. The url parameter is discarded.

action: notify.all_phones
data:
  title: "Cold Start Attempt"
  message: "Force close app, then tap."
  data:
    url: "http://host_ip_goes_here:8123/frigate?index=/review/review_id_goes_here"
    tag: "cold_start_test"

I get the same behavior when using url: "/frigate/review/review_id_goes_here". It works when the app is already open, it doesn't work when the app is not already open [when I click].

In case it matters somehow, I am using Frigate 0.16.3; but this does not seem to be a Frigate issue. I am using an unauthenticated (port 5000) access point on the remote Frigate server. As mentioned earlier, this works well if the Home Assistant Companion app is already open when the notification gets clicked.
