Beta hasn’t even had addons enabled for a week yet.

There isn’t Beta support as there isn’t a current stable working version yet.

Once it is working, and stable, then feedback, issues will be taken.

This is why we made it private. We had it public but people was downloading it and giving these reports as we are actively working on it and it's being counterproductive. So from now on each classic version will be private until they are stable.
