There are problems with the twitch chat right now
And twitch isn’t fixing them. If you find yourself unable to post on the twitch chat, the best I can suggest is using the Popout contingency chat. It’s for emergencies only.
In the meantime, I have contacted twitch support regarding the issue. If it has affected you, then please do the same. The more people complain, the faster they’ll fix it (i’d imagine). Sorry for the issues.
Love, Cats
