The problem

The preload stream option for live view of cameras in picture-entity cards cannot be changed on Android in Chrome or the official Companion app.

I use picture-entity cards to display camera feeds with a live view, e.g.

elements:
  - camera_image: camera.driveway
    camera_view: live
    entity: camera.driveway
    style:
      height: 100%
      left: 50%
      top: 50%
      width: 100%
    type: image
image: /local/ui_resources/dummyimage.jpg
theme: Backend-selected
type: picture-elements

1 Using the official companion app on my phone: the preload stream checkbox is unchecked and I am unable to check the option from within the app. This occurs regardless of whether I access HA through internal / external url (Nabu Casa).
2 Using the full Chrome browser on the same phone: the preload stream checkbox is checked and I am unable to uncheck the option. This occurs regardless of user account and url used to access.

Expected behavior

The preload stream checkbox should be accessible, and respond to user input consistently regardless of platform.
On the Chromebook using the full Chrome browser: the preload stream checkbox is unchecked and I am able to change it as required. This works for both user accounts and regardless of url used to access, This is the expected behaviour.

Steps to reproduce

1. Add basic picture-elements card (example above) with live camera view.
2. Using the versions indicated above, access the live view with a single touch / click on the card and attempt to change the option.
