Trying to find a solution to this issue. I figured vtuber kit just needed to be reset but redeems from twitch to vtuber kit don't seem to be working at all...

That's exactly how they should work. Try generating a new OAuth key. Make sure all the names match exactly. Capital letters and spaces count.

I had the same issue when setting up my outfit redeems, what worked for me was fully closing the application and reopening instead of using the restart button
