Quoted from yzfguy:
Got a credit dot, and figured it must be the right scoop which I rarely hit. So I'm not sure how to see which switch is causing the credit dot. Hitting the scoop didn't immediately clear it. Just found a "clear service notifications" option. So I cleared it, but then had to restart the game. Just wondering how to see what triggers a credit dot.
Next time that happens, go into the serive menu and select the Error Report. That will tell you what is going on. You can look at it even before a credit dot is issued and see any potential issues. It could be a jam opto, or shooter lane switch issue.
Hope that helps.
