Issue with blog post permissions

[Gary O]

We have a specific issue with some users in our blog posts.

We use blogs for posting company updates. Users can like and comment.

As of today, 4 users have come to say they can like other blog posts, but not a specific one. This is not 1 specific blog post, which post they can and can't like is different for each user, looks random.

One user could like yesterday, and cannot this morning on a blog post, and no permissions have been reconfigured.

All users are part of space permission groups, and the permissions for blog posts and comments are enabled.

Blog posts themselves don't have any restrictions and are all created in the same way

We can't figure out what's happening

Does anyone have any info on what this might be?
