heya! if you are in version 2.0.18 you need to enable alt twitch connection, set the channel points redeem and then save and restart vtspog given that one is running still through the old api. If you are on beta 2.0.55 keep the alt twitch connection DISABLED and that should do the trick
remember also to enable the text input on the channel point redeem. If still doesnt work after all that come through to the vtspog discord server, make a thread on support ideally showing the error in motion in a screen recording and what you have already set up and we can look at it together there
