Q70 HDMI inputs do not work

[steftodor]

I am using the component with my 2019 Q70 QLED tv.

For the most part everything works without issue (turning on off the tv, changing the apps, and changing the volume).
However when I go to change to an hdmi input the tv will either not respond or ask me to approve the device again. After approving it again, nothing happens.

Here is my YMAL:
`media_player:

• platform: samsungtv_custom

  port: 8002

  applist: "YouTube, Apple TV, Plex, Prime Video, Netflix, Spotify"
  protocol: ctl_qled
  timeout: 25`

This appers in the logs once I select an hdmi
