Cannot resolve a parent pom deployed in Github Packages

Question

I created a parent POM to be shared by multiple projects. It is a POM-only project. Here is what it is like.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <modelVersion>4.0.0</modelVersion>

    <groupId>myorg</groupId>
    <artifactId>project-parent</artifactId>
    <version>0.2.8</version>
    <packaging>pom</packaging>

    <name>project-parent</name>
    <description>Parent pom providing dependency and plugin management for services built with Maven
    </description>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.7.0</version>
        <relativePath/>
    </parent>

    <distributionManagement>
        <repository>
            <id>github</id>
            <name>GitHub OWNER Apache Maven Packages</name>
            <url>https://maven.pkg.github.com/[OWNER]/my-repo</url>
        </repository>
    </distributionManagement>
</project>

I used GitHub Actions to deploy the pom to GitHub Packages. From the log, I could see the deployment was successful.

However, when I referenced it in a child POM, I got the following error.

 Could not find artifact myorg:project-parent:pom:0.2.8 in github (https://maven.pkg.github.com/[OWNER]/my-repo) and 'parent.relativePath' points at no local POM @ line 13, column 10

I referenced the repository in the sub-project's POM, like this

   <parent>
    <groupId>myorg</groupId>
    <artifactId>project-parent</artifactId>
    <version>0.2.8</version>
    <relativePath/>
   </parent>
   ...
   <repositories>
    <repository>
        <id>github</id>
        <name>GitHub OWNER Apache Maven Packages</name>
        <url>https://maven.pkg.github.com/[OWNER]/my-repo</url>
    </repository>
   </repositories>

I stored my GitHub credential in the local settings.xml for the child project. I stored the credentiali in the GitHub Secrets for Actions. They worked as expected.

I've tried many things:

went thru many postings on this site
checked the distribution repository setting in the parent pom
downloaded the parent pom files directly from GitHub Packages, and the file was correct
checked the depedency repository setting in the child pom
Checked the Maven cmd used in GitHub Actions, mvn --batch-mode deploy

Can someone please tell me what I could have missed? Thanks!

UPDATE - I published the parent pom to CodeArtifact and it just worked. I guess GitHub Packages might have a bug.
