That said, the go-to solution for troubleshooting is refreshing the page. However, there are some cases when it’s not.
I can’t see anything in the “Orbital Transformations” playground.
This is totally normal. Simply click on the orbital information panel to change any of the two orbital. On the panel that is generated on the right hand side, you do not need to do anything. Just click “OK.” You will see the orbital.
Note: There are some invalid transformations. Those are blocked, and the right hand side panel will turn pink to alert you if you attempt to create them.
