After updating to Discourse 3.1.0 beta6, user flash reports that avatar photos are missing, particularly on mobile and in post threads, despite successful avatar refresh and rebake attempts. The avatars are visible on the main desktop page but not in threads, with only default avatars appearing. The URL for avatars is correct, pointing to the expected location, but the issue persists unless a user reposts a new photo. Stephen asks about troubleshooting steps, and pfaffman requests more details, including the site URL and examples of affected users. flash notes the discrepancy between desktop and mobile visibility and offers access to the private site for further investigation.
