Avatar Disappeared From Most User Profiles (Sept 2021)

The avatar for most of the user profiles (including mine) disappeared from their badges about a week ago. When I go to Settings | Avatar in my user profile I see that my choices are now limited to:

Is this a temporary glitch in the forum software, or are these the only profile avatars that are available to most users now?

I understand from Dell-BradL's 15-Jun-2021 post <here> that users who have reached Level 7 or have become a TechExpert are currently allowed to add a custom profile avatar.  If other users can only choose one of the above avatars now then perhaps the ability to upload a custom profile picture could be expanded to everyone so that posts from a given individual are easier to identify in the forum.
