@ryanbr Is this working in other channels now or is there a specific fix we need to uplift?

[ryanbr]

Just confirming with the user via twitter, thanks for the reminder @rebron :)

It seems fine now. I was able to use tweetdeck

@rebron @ryanbr can we close this off?

[ryanbr]

Yup, resolved.

Fixed was removing all *.twitter.com from Preferences json then let Brave rebuild it again. Not sure caused the issue, but its resolved.
