I had previously linked my twitch account to my brave account, but changed my twitch username since. As I didn’t see an obvious option to change the details of the linked account, I deleted the link to my brave rewards and tried to re-add it under the corrected new username. I was confronted with a message that read "Could not authenticate you from RegisterTwitchChannel because “Invalid credentials”
I read a few other posts describing a similar error on here, so I tried to clear my cache and and try again, I did this a few times with no success.
On an unrelated note, I connected my youtube channel but when I goto the actual youtube page it shows the creator as “on Youtube” without any username or verified status.
