Hello!
I am really sorry that you are having these issues with the program and I can definitely understand the frustration!
This issue should have been resolved in an earlier version! It is weird that this is happening to you!
I would recommend the following steps:
- Deauthenticate Twitch and try authenticating again.
- Join the official discord to make a post about this issue, so we can support with the help of screenshots and logs
As for YouTube, it should work by creating triggers with the "YouTube"-Source selected, then the dropdown should show you which events you can select. Sadly currently there is an issue with the YouTube connection, where I have to resolve it with google, which likely will take a while for now :/ (Google usually takes very long to take care of matters of small developers like me)
A workaround is just having Streamlabs or Streamelements connected, since those should forward YouTube events aswell, without needing YouTube connected directly!
I hope I could help you with your issue for now and hope we can resolve this quickly!
