Play on Roku functionality now broken - devastating!

Hi folks, I’m dealing with an issue that unfortunately has immobilized a museum exhibition that is about to open in two days. I would really appreciate any help. My fault for using proprietary devices that update on their own :’’’((((

The Play on Roku feature is broken for me (with Roku Streaming Stick 4k) in the latest software version: 11.5.0 (build 4235-CU), used with the Home Assistant Roku integration. Roku - Home Assistant

I’ve tried the latest version of HomeAssistant and the integration, so I know that it isn’t broken due to changes in those.

The functinoality still works on a Roku Streaming Stick 4k device that still has 11.0.0 build 4193-CU.

Media is triggered through HomeAssistant with the Roku integration.

On a device with 11.0.0 build 4193-CU it executes without an issue.

On the 11.5.0, the Play on Roku splash screen pops up for two seconds, and then crashes and just shows the previous screen that was visible on Roku (dashboard, for example).

For reference, this is the YAML code that triggers the event through the Home Assistant Roku integration.

service: media_player.play_media
target:
  entity_id: media_player.roku_1
data:
  media_content_id: http://192.168.100.6:8080/video/fire.mp4
  media_content_type: url

THANK YOU IN ADVANCE FOR ANY ADVICE!

I got a response from a Roku developer. tldr: they disabled this functionality for third party apps.

Unless they allow downgrade, you will need to replace upgraded units with units on old firmware or replace with RasPi or PC.

Any update on this?
