Record Id is not populating to LWC in Record Page in Community (Experience Cloud)

Question

I have a problem capturing the record id from a record page in communities.

I followed Get RecordId in LWC From Community Page intructions but it's not working for me and i saw that is not working for more people.

As my LWC contains a lot of content i created a simple LWC that shows only the Record ID

ShowRecordId LWC

HTML

    <template>
        <p>Record Id: {recordId}</p>
    </template>

JS

    import { LightningElement, api } from 'lwc';
    
    export default class ShowRecordId extends LightningElement {
        @api recordId;
    }

META

    <?xml version="1.0" encoding="UTF-8"?>
    <LightningComponentBundle xmlns="http://soap.sforce.com/2006/04/metadata">
        <apiVersion>58.0</apiVersion>
        <isExposed>true</isExposed>
        <masterLabel>Record Id</masterLabel>
        <targets>
            <target>lightning__RecordPage</target>
            <target>lightningCommunity__Page</target>
            <target>lightningCommunity__Default</target>
        </targets>
        <targetConfigs>
            <targetConfig targets="lightning__RecordPage">
                <property name="recordId" type="String" label="Record ID" description="Should be set to {!recordId}"/>            
            </targetConfig>
            <targetConfig targets="lightningCommunity__Default">
                <property name="recordId" type="String" label="Record ID" description="Should be set to {!recordId}"/>            
            </targetConfig>
        </targetConfigs>
    </LightningComponentBundle>

Result

I access to the page customer following the url

I added in the record page a standard record component to show that this is capturing the recordId from the context

Also I have seen that before publish I see an error that the record id is not being shown.

Here I just duplicated the ShowRecordId component in the Record Page

Error: Experience Builder can't display this component because its record ID isn't well formed. In the Propery Editor,enter a well-formed ID in the Record Id field --- for example {!recordId}.

But in this case here I put {!recordId}
