Hello Sandra97,
Sorry for the inconvenience you're experiencing.
The issue arises because when a page loads with the ?tmpl=component parameter, Joomla only renders the component's output. This intentionally excludes the template elements, including the <head> section where your manifest and JavaScript files are defined.
Consequently, your PWA manifest and datepicker scripts aren't being loaded. This behavior is by design, as ?tmpl=component is typically used for AJAX calls or embedded content where the full template isn't needed.
To resolve this, you can either include the necessary scripts directly within the component's layout or avoid using the ?tmpl=component parameter on pages that rely on your template's assets.
We appreciate your understanding.
Best regards
