[LiveComponent] Getting "Cannot find a template matching "a67ec1ad40dd8f6b6934cb852ed6d2f9". Cache may be corrupt."... all the time

[gremo]

I've created a dashboard with a few live components, some of them configured with the polling option. The dashboard is running on a tablet, in Kiosk mode, so it can't be refreshed easly (at least, it will be refreshed at some time interval, i.e. 30 minutes).

The error happens in dev mode but, most important, in production mode. It goes away as soon as I refresh the page (in both modes).

Every time I deploy a new version of my app I get the following error:

Cannot find a template matching "a67ec1ad40dd8f6b6934cb852ed6d2f9". Cache may be corrupt. at /var/www/html/vendor/symfony/ux-live-component/src/Twig/TemplateMap.php:33

Source of exception is TemplateMap.php and details is:

{
    "class": "RuntimeException",
    "message": "Cannot find a template matching \"e04c41ae1f6221d0e0371055ff8d5cb2\". Cache may be corrupt.",

    ]
}

I think it's something related to components configured with polling. Any help is really important here. Thanks.
