I saw that there is a topic regarding this issue already, but you told that you could not reproduce the issue. I’m currently experiencing the same issue as the user: modpwn.
I’ve installed the OBS-chat into my OBs and it is working great, but it does not show there icons in front of people’s names.
OBS Chat relies on Twitch to notify our server with a mode change when you become a mod. It can take 30 seconds after joining a channel to show up as a mod on OBS chat due to this.
