The blueprint does not work anymore. It shows the following errors in the logs:

same here, a lot of templates stopped working with similar error or with:

Error while processing template: Template<template=({% if states('sensor.plastics_days')|float > 1 %} none {% elif is_state("calendar.plastics", "on") %} red {% else %} yellow {% endif %}) renders=336>
Error while processing template: Template<template=({% if states('sensor.plastics_days')|float > 1 %} Next due date in: {{states('sensor.plastics_days')}} days {% elif is_state("calendar.plastics", "on") %} Due day is Today {% else %} Due day is Tomorrow {% endif %}) renders=336>

That probably has to do with this change:

Progress is appreciated but this has indefinitely ended part of my setup, as service call responses are not visible on the dashboard. I used to use the data in attributes on a markdown card, have no fix. I just adapted an automation to the new system, so not a total loss
