Ever since 2024.11.3, whenever I cast my dashboard to a Chromecast Ultra, every markdown card is blank. All other cards display as expected. The markdown cards will display my Google TV with Chromecast, but the resolution is out of whack, so I can’t use that as a solution. Accessing HA from my PC or via the App, all cards are displayed as expected.
I downgraded HA to 2024.11.2 and still the same issue, so I suspect that something changed with the Chromecast Ultra firmware. I haven’t changed anything in configuration.yaml. I reboot and reset the Chromecast to no avail. I’m at a loss as to possible solutions.

is_state(‘sun.sun’,‘above_horizon’) %} Sunset at {{
as_timestamp(state_attr(“sun.sun”, “next_setting”)) | timestamp_custom(‘%-I:%M
%p’, local=True) }}. {% else %} Sunrise at {{
as_timestamp(state_attr(‘sun.sun’, ‘next_rising’)) | timestamp_custom(‘%-I:%M
%p’, local=True) }}. {% endif %}
