Downloaded addon. Switched to various specs. Opened bank. Clicked on portrait to get highlighted string. Copied highlighted string. Pasted into the box. Flashed briefly then nothing. Character finally shows up on list. Click on character. Nothing. Can’t get this to work at all even with premium subscription.
When you paste into the box, it will automatically load your character’s data. Then at the top of the page you should see 4 links to the different optimization tools (or you can just scroll down the page to the tool that you wish to use).
Are you not seeing that? What web browser are you using?
