Streamers cannot use own follower emotes
Streamers cannot follow their own channels. As a result we cannot use emotes that we have placed in the follower emote slot
If you are having issues with follower emotes please reach out to our team at help.twitch.tv
I will say that sometimes it's browser side as to why the emotes are not loading. I would suggest some browser troubleshooting, because streamers should be able to use their own follower emotes.
