Hello, a few months ago my BTTV stopped working and I thought I would just wait for the problem to work itself out but it never did. The problem is that only ONE message is shown in chat at a time. Every time a new message is sent it deletes the last message and the new message shows, and that just repeats.
I uninstalled all my extensions and it still didn’t work… so I deleted all browsing data including browsing history, download history, cookies and other site and plugin data, cached images and files, autofill form data, hosted app data, and content licenses. Now it works!
