That’s mine. It was apparently a permissions issue with my profile (missing crown on the profile picture). @bernardoghazi fixed it (thank you!), but ~2 months later PMS broke again and the options/settings underneath “Settings > Plex Media Server” disappeared (different from my original, rarer issue, where the entire “Plex Media Server” row including the “Plex Media Server” heading disappeared). Reinstalled PMS, issue persisted. Removed PIN, options/settings reappeared but PMS stopped after changing storage location. Restarted Shield, PMS resumed but options/settings disappeared again. Reconfigured PIN, options/settings reappeared.
